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 = 116, x = 12.5, and s = 6.35. Does this data indicate that average daily zinc intake in the population of all males age 65−74 falls below the recommended allowance?

Using the information provided in the SPSS output. You are asked to make a decision about whether to reject the null hypothesis that the population value of gamma equals 0 (i.e., that there is no ordinary association in the population between frequency of prayer and health). If alpha = 0.05 and you use a non-directional alternative hypothesis, which of the following is true?) A. Since the p-value is larger than alpha, you do not reject the null hypothesis B. Since the p-value is less than alpha, you do not reject the null hypothesis C. Since the p-value is larger than alpha, you reject the null hypothesis. D. Since the p-value is less than alpha, you reject the null hypothesis

When consumers apply for credit cards, their credit is rated using FICO scores. A random sample of credit ratings is obtained, and the FICO scores are summarized with these statistics: n=35, ?̅=660.3, s=95.9. Use ?=0.05 and conduct a two-tailed hypothesis test to test the claim that the mean credit score (of the general population) is equal to 700. a) Write the two hypotheses for the problem. b) Which conditions have to be satisfied in order to conduct the test for the population mean? c) Find the t test statistic and associated p-value. d) Make a sketch of the distribution indicating the t test statistic and the p-value. e) In the context of the problem, write a conclusion to the study.
