In the US 50% of 17 year-old males are 176 cm tall or higher. In Mr. Kellar’s classroom 9 out of 13 males had a height of 176 cm or more. Mr. Kellar claims that his classroom has a higher percentage of boys taller than 176 cm.
Select the appropriate null and alternate hypotheses.
H0: p̂ = 0.5
H0: p̂ > 0.692
H1: p̂ > 0.5
H1: p̂ = 0.692

Based on a significance level of 0.05 do you accept or reject H0?
p-value > α, accept H0
p-value < α, reject H0
p-value > α, reject H0
p-value < α, accept H0

Mr. Kellar asked 29 of his students how many hours of sleep they got on a school night. The standard deviation of the class was 1.33 hours. Assuming the high school has a standard deviation of 1.1 hours is Mr. Kellar’s class standard deviation different than the high school?
