Question

Several years ago, the mean height of women 20 years of age or older was 63.7 inches. Suppose that a random sample of 45 women who are 20 years of age or older today results in a mean height of 64.7 inches. State the appropriate null and alternative hypotheses to assess whether women are taller today. Suppose the P-value for this test is 0.08. Explain what this value represents. Write a conclusion for this hypothesis test assuming an alpha = 0.10 level of significance. H_0: mu = 63.7 in. versus H_1: mu > 63.7 in. H_0: 63.7 in. versus H_1; mu notequalto 63.7 in. H_0: mu = 64.7 in. versus H_1: mu 64.7 in. H_0: mu = 63.7 in. versus H_1: mu

Explanation / Answer

B) AS THE SIGNIFICANCE LEVEL = 0.10

AND THE P VALUE = 0.08

AS THE P VALUE IS LESS THEN THE SIGNIFICANCE LEVEL WE WILL NOT REJECT THE NULL HYPOTHESIS

HENCE THE INTERPRETATION WILL BE THE OPTION A

HENCE OPTION A IS CORRECT
