There is a 13.3% chance that a sample of 200 U.S. students in grades 9 through 12 who attend public and private school will have 11% or fewer obese students if 13.7% of the population is obese this year. (Option D)
<u>Explanation:</u>
From the given information it is observed that the 2013 national Youth Risk Behavioural Survey reported that 13.7 percent of US students in grades 9 through the grade 12 who attended the public school were obese.
Consider the random sample of 200 US students and find that 11 percent are obesed. The Null and alternative hypothesis are
Null hypothesis, = 0.137, Alternative hypothesis, = p less than 0.137
Thus, the value of p is 0.133
12, 16 18, 24, 28, 31, 32, 32, 32
Mode: 32
Mean: 12 + 16 + 18 + 24 + 28 + 31 + 32 + 32 + 32 = 225 ÷ 9 = 25
Mean: 25
Median: 28
Brainly only allows you to ask one question, however I will answer the first few.
Mean = 146.667
This is because if you add 810+10+12+15+15+18 you get 880. Divide that by 6 (there are 6 numbers) and you get 146.

Answer:
a. probability, when the null hypothesis is true, of obtaining a sample result that is at least as unlikely as what is observed
Step-by-step explanation:
In Statistics, a p-value also known as the probability value is the probability, when the null hypothesis is true, of obtaining a sample result that is at least as unlikely as what is observed.
The p-values can be calculated by using spreadsheets, statistical software and p-value tables and is widely used in research fields such as economics, physics, sociology, accounting etc.
The p-value can be mathematically expressed as a function of the null hypothesis, H and the random variable, X.
