Test the following claim. Identify the null hypothesis, alternative hypothesis, test statistic, critical value(s), conclusion about the null hypothesis, and final conclusion that addresses the original claim. Tests of older baseballs showed that when dropped 20 ft onto a concrete surface, they bounced an average of 236.6 cm. In a test of 40 new baseballs, the bounce heights had a mean of 234.5 cm. Assume that the standard deviation of bounce heights of all new baseballs is 4.5 cm. Use a 0.05 significance level to test the claim that the new baseballs have bounce heights with a mean different from 236.6 cm. Are the new baseballs different? What is the value of the test statistic? (You will need to decide whether to use z-scores or t-scores) z or t= (Round to two decimal places as needed.) Identify the critical value(s) of z or t. z or t= (Round to two decimal places as needed. Use a comma to separate answers as needed.) V Ho. There V sufficient evidence to support the claim that the new baseballs are different.
