Question

Use a t-test to test the claim about the population mean mu at the given level of significance alpha using the given sample statistics. Assume the population is normally distributed Claim. mu notequalto 51, 300: alpha = 0.05 Sample statistics: x bar = 50, 245, s = 1500, n = 16 What are the null and alternative hypotheses? Choose the correct answer below. A. H_0: mu notequalto 51, 300 H_a: mu = 51, 300 B. H_0: mu lessthanorequalto 51, 300 H_a: mu > 51, 300 C. H_0: mu = 51, 300 H_a: mu notequalto 51, 300 D. H_0: mu greaterthanorequalto 51, 300 H_a: mu

Explanation / Answer

Null and Alternative Hypothesis:

Answer: Option C

Test Statistics = ( x bar – Mew)/(s/sqrt(n))

                         = (50245-51300)/(1500/sqrt(16))

                         = -2.81

Answer:

The standardized test statistics is -2.81
