Describe the sampling distribution of ModifyingAbove p with caret. Assume the size of the population is 25 comma 000. nequals400, pequals0.3 Choose the phrase that best describes the shape of the sampling distribution of ModifyingAbove p with caret below. A. Approximately normal because n less than or equals 0.05 Upper N and np (1 minus p )greater than or equals 10. B. Not normal because n less than or equals 0.05 Upper N and np (1 minus p )greater than or equals 10. C. Approximately normal because n less than or equals 0.05 Upper N and np (1 minus p )less than 10. D. Not normal because n less than or equals 0.05 Upper N and np (1 minus p )less than 10. Determine the mean of the sampling distribution of ModifyingAbove p with caret. mu Subscript ModifyingAbove p with caret Baseline equals nothing (Round to one decimal place as needed.) Determine the standard deviation of the sampling distribution of ModifyingAbove p with caret. sigma Subscript ModifyingAbove p with caret Baseline equals nothing (Round to three decimal places as needed.)

According to a research study, parents with young children slept 6.4 hours each night last year, on average. a random sample of 18 parents with young children was surveyed and the mean amount of time per night each parent slept was 6.8. this data has a sample standard deviation of 0.9. (assume that the scores are normally distributed.) researchers conduct a one-mean hypothesis at the 5% significance level, to test if the mean amount of time parents with young children sleep per night is greater than the mean amount of time last year. the null and alternative hypotheses are h0: μ=6.4 and ha: μ> 6.4, which is a right-tailed test. the test statistic is determined to be t0=1.89 using the partial t-table below, determine the critical value(s). if there is only one critical value, leave the second answer box blank.
