The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65-74 yearsin 111, x 12.7, and s 6.55. Does this data indicate that average daily zinc intake in the population of all males age 65-74 falls below the recommended allowance? (Use a- 0.05.) State the appropriate null and alternative hypotheses. O Hot = 15 " 15 O Hgt - 15 HHS 15 Hgl - 15 HHe 15 O Hgi - 15 Caleulate the test statistic and determine the Pvalue.

Question

The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65-74 years: n = 111, x = 12.7, ands = 6.55. Does this data indicate that average daily zinc intake in the population of all males age 65-74 falls below the recommended allowance? (Use a = 0.05.) State the appropriate null and alternative hypotheses. O Ho: u = 15 H3i u = 15 O Hoi u = 15 Hi us 15 O Ho: 4 = 15 Ha: l < 15 O Hoi H = 15 H: u > 15 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) P-value = 0 State the conclusion in the problem context. O Do not reject the null hypothesis. There is sufficient evidence that average daily zinc intake falls below 15 mg/day. O Reject the null hypothesis. There is not sufficient evidence that average daily zinc intake falls below 15 mg/day. O Do not reject the null hypothesis. There is not sufficient evidence that average daily zinc intake falls below 15 mg/day. O Reject the null hypothesis. There is sufficient evidence that average daily zinc intake falls below 15 mg/day.
