Can someone help me with elementary statistics problem?
Hi! I just can't figure out the steps to solve this problem. I have a TI84+ that I am supposed to be using but I cannot find the steps to figure this one out. In a study of pregnant women and their ability to correctly predict the sex of their baby, 56 of the pregnant women had 12 years of education or less, and 42.9% of them correctly predicted the sex of their baby. Use a 0.05 significance level to test the claim that these women have no ability to predict the sex of their baby, and the results are not significantly different from those that would be expected with random guesses. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution. Hope someone can help! Thanks :) I'm really looking for the calculator steps for the most part.
What are the effects of vices on the students studies in high school level?
there are many effects of vices on students in the secondary level some are: - the students find it that if they have a vice they become cool - the studies of the students are left out - the concentration of the students in studying fades away - the students become lazy in school - it depends on the vice but if it's something like cigarette.. the health of the student is also affected,, vices may lead to diseases - the relationship of the student with his parents become distant - the relationship of the student with the one (peers) that influenced them becomes closer - the student starts to rebel - the student changes his perspectives and beliefs - the student will find the vice addictive and hard to let go -the future of the student becomes dangerously uncertain -good relationship with false friends - the student always gets into trouble and becomes problematic which will even cause him to have more vices - the student will find the vice as a stress reliever however, there's always a time for a change and the student can still change his life... just seek for God's guidance :D
I want to study abroad, but I do not have enough money. What can I do?
You can apply for a scholarship …I'm from india and I didn't have any money with me when decided to study abroad . After a long search for some scholarships I found so many chances all over the world . I didn't have money and time to prepare for IELTS or any other English proficiency exams. So I couldn't apply for a number of scholarships . But I found Turkey govt. Scholarship (Home - Türkiye Bursları )doesn't need that kind of exams and it's application system is very easy . So I applied for this scholarship . After one month they sent me a message that my application was successful and they invited me for an interview in Delhi. I went there alone after borrowing some money from friends (it's like 2000km away from my home). The interview was very easy for me . After one and half month that beautiful news came to my email .. I was just jumping and dancing when I see that… then I got visa and flight ticket for free ..and ..yup ..now I'm in Turkey… I'm getting a scholarship of 250$ every month besides the food ,accommodation and health insurance. I'm studying well…. Yea . Even poor can study wherever if he have academic caliber.. my dream is studying masters degree in Oxford or Cambridge university. I will study hard until I get a scholarship to study in the no. 1 unv. In the world..In nutshell, you can study anything anywhere if you really want to do it… good luckFind the best scholarship for you from this website https://goo.gl/MwNvxs
