Identify the null hypothesis, alternative hypothesis, critical value, test statistic, conclusion about the null hypothesis, and final conclusion that addresses the original claim.
22) A nationwide study of American homeowners revealed that 64%
have one or more lawn mowers. A lawn equipment manufacturer,
located in Omaha, feels the estimate is too low
for households in Omaha. Can the value 0.64 be rejected if a survey
of 490 homes in
Omaha yields 331 with one or more lawn mowers? Use = 0.05.

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A test of sobriety involves measuring the subject's motor skills. A study of n = 20 randomly selected sober subjects take the test and produce a mean score of X = 41.0, and we know that o = 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is...
