A random sample of 120 females results in 20 of them are cigarette smokers. A random sample of 150 males results in 26 of them are cigarette smokers. A dietician tests to determine if the proportion of female smokers is lower than the proportion of male smokers. A hypothesis test was conducted at the 5% significance level and the p-value was found to be 0.456. Which of the below is the conclusion for this test?

Suppose in a sample of 50 randomly selected children, 40 consume more than 8 hours of screen time per day. Suppose in a sample of 50 randomly selected adults, 42 consume more than 8 hours of screen time per day. Is there evidence to suggest that the proportion of children and the proportion of adults that consume more than 8 hours of screen time per day is significantly different? Find the p-value of this test. StatKey
