Help with Stats question?
Hard body : Arithmetic mean : Xbar = ΣX / N = 296 / 17 = 17.4 Standard deviation : s = √ [Σ(X - Xbar)^2 / N] = √ [96.12 / 17] = 2.38 Variance : s^2 = 5.66 Degrees of freedom = 17 - 1 = 16 -------------------- Soft body : Xbar = 88 / 6 = 14.7 s = √ [113.34 / 6] = 4.35 s^2 = 18.92 Degrees of freedom = 6 - 1 = 5 -------------------- Using the F distribution : F = (larger variance) / (smaller variance) = 18.92 / 5.66 = 3.34 (with v1 = 5 and v2 = 16) This is a two-tailed test because the null hypothesis is that there is no difference between the variances. With a 5% probability limit, each tail area = 0.025. Looking up a table of the F distribution for v1 = 5 and v2 = 16, the value given for 0.025 is 3.50. The observed value of 3.34 is less than 3.50, so it lies between the 5% probability limits. Thus, the null hypothesis is accepted, so the claim that there is a difference in the variances of the weights of the two types CANNOT be substantiated, at the 0.05 level of confidence. (My apologies to statistical experts if that is incorrect)

SURF BOARD HEIGHT WEIGHT QUESTIONS PLEASE HELP!!?
Many decades ago I started surfing on a short board. I surfed every day I could. I got pounded, free fell over the falls, would be in the water for hours and lucky to catch a single wave...but I hung in there. I was determined...and had the focus and desire to learn. Eventually I got pretty good...not pro-level...but good enough. If I had to start over...I would do it differently with what I know. I also teach surfing now..and would never start anyone on a short board. With that being said...I do know you can learn on a short board. The road is longer and alot more difficult...but it can be done. You have to have a strong desire, determination, spend alot of time in the water, be in decent shape and not be the type of person that gives up easily. One of the problems with surfing...is balancing how well your board FLOATS you and how RESPONSIVE your board is. Generally the thicker the board is...the less responsive it will be. Since it sounds like since you're pretty decent on a skim board you are probably used to alot of responsiveness. You tried your friends 8 footer and found it not responsive enough...(when I surfed my first longboard...I found it soooo easy to catch waves...but had a hard time figuring how to turn the darn thing). Learning on a short board you will not have much float. That means harder to get into waves...which means less waves. If you can live with that...then go ahead. As a starting point...what Surfammo said on the dimensions seem reasonable...thickness - 2.5 to 3 inches...height - 6'6" to 6'10". But I think talking to your LOCAL SHAPERS in your area would be the BEST ADVICE. good luck to you... - mahalo -
Weight question :) x?
You are not huge at all! You sound more like borderline anorexic. At your age you need as many vitamins and such as you can get, your body needs nutrition in order to grow strong and healthy. Don't starve yourself! Your hair falling out is a sure sign of vitamin deficiency- your body is very unhealthy! When you eat very small amounts, if you increase your food intake your body will store food and fat, waiting for you to starve it again. you gain much more weight by restricting yourself so much than you would if you just ate heaps of small meals all throughout the day. You should consider this.
Does yoga help with weight loss?
Yes It is. I lost 3 Kgs in less than a month. It worked out for me in an effective manner. I even hit 108 per day, and the change is very visible. You can start with minimum 7 rounds per day and gradually increase the count. I used to pursue running and sometimes gym and sometimes diet. But this time i didnt care about anything, In fact i increased my Carb loading. The change was phenomenal and u can feel it along the day after workout, all the muscles in active state.Before you start any weight loss program, you should know there are about 3,500 calories in 1 pound of fat. S0, you need to reduce your daily calories by 250 to 500 in order to achieve ½ to 1 pound of weight loss per week. Using the numbers from this yoga study, a 138-pound person needs to do Surya Namaskar for 18 minutes to burn 250 calories, 25 minutes to burn 350 calories and 40 minutes to burn 500 calories.Surya Namaskar- 30-minutes workout calorie meterHow much calories are you burning in your 30 minute workout?Weight lifting = 199 caloriesTennis = 232 caloriesBasketball = 265 caloriesBeach volleyball = 265 caloriesFootball = 298 caloriesBicycling (14 – 15.9 mph) = 331 caloriesRock climbing = 364 caloriesRunning (7.5mph) = 414 caloriesSurya Namaskar = 417 caloriesSurya Namaskar calorie Calculation:One round of Surya Namaskar burns upto 13.90 calories for an average weighing person. You can now set the target for yourself. Slowly you can increase the number of rounds of surya namaskar to 108. By the time you reach this number, you will find a leaner you.288 yoga poses in 12 minutes!One round of Sun Salutation consists of 12 yogaposes.One set consists of two rounds of SunSalutation:first stretching the right side of yourbody and then the left side. So, when you do 12sets of Sun Salutation, you are completing 12 setsx 2 rounds in each set x 12 yoga poses in each= 288 yoga poses in 12 to 15 minutes.

Annoying Questions About Weight Loss:1. Medical Emergency Questions. Holy shit, if you’re bleeding, get on the telephone and call medical emergency straight away!2. Medically complicated persons asking exercise questions.

Asking for free advice on the internet is not for you! 3. Minors/Children asking weight loss questions. Bad bad bad.4. People that weigh nothing and want to lose weight (clearly an eating disorder question and OUT OF SCOPE for an internet forum. See a doctor!). This is a tough one because some of these askers need help, but some of these askers are literally seeking eating disorders.5. Super personal unique questions regarding weight loss where the person lists all their intake data. “I’m 5’6 and weigh 100 pounds and ….” That’s a session. If you have questions like this then we are on the clock.6. Robot food questions or testimonials which is bad enough, but where the end goal is to build their downline. Fad diet mania and all of the canned leading questions to suck everyone in from the person selling the fad diet crap.
