Answer: Yes
Explanation: a statement that the values of two mathematical expressions are equal (indicated by the sign =).
Two values (6 and 3) are being brought together for another value represented by the = symbol making this an equation
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
The answer is 4y^4.
