The distribution of TV times in normal with a population standard deviation of 2 hours. Last year a sample of 100 preschool children had a mean of 5.8 hours of TV watching per day. Test to determine if the average time preschool children spend watching TV per day has decreased at the 0.01 significance level. Part A - H0: μ =[BLANK-1] Part B - Ha: μ [BLANK-2] [BLANK-3] Part C - State alpha [BLANK-4] Part D - Reject null if [BLANK-5] [BLANK-6] [BLANK-7] (Answer f should be the inequality symbol, and Answer g should be the value.) Part E - The test statistic is [BLANK-8]. Part F - Write the decision [BLANK-9] Either Reject the null or Accept the null Part G - At α = [BLANK-10], there is evidence to [BLANK-11]
Accоrding tо а study repоrted by the Nаtionаl Center for Health Statistics, 3.62% of women aged 30-34 who had a child, gave birth to twins in the year 2018. 300 women aged 30 - 34 having a child were selected in a sample. Part A - What is the sampling distribution of p^? The mean is [BLANK-1] and the standard deviation is [BLANK-2]. Give both these answers to 4 decimal places. Part B - Find the appropriate z-score for this problem. z = [BLANK-3] Part C - Find the probability more than 6% of the women in the sample had twins. [BLANK-4]
