What sampling distribution will you use? O Student'st chi-square uniform O normal What are the degrees of freedom? (c) Estimate the P-value of the sample test statistic. O P-value > 0.100 O 0.050 < P-value < 0.100 O 0.025 < P-value < 0.050 O 0.010 < P-value < 0.025 O 0.005 < P-value < 0.010 O P-value < 0.005 (d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis of independence? Since the P-value > a, we fail to reject the null hypothesis. Since the P-value > a, we reject the null hypothesis. Since the P-value s a, we reject the null hypothesis. nualue < g we fail to reject the null hypothesis.

Snoop Incorporated is a firm that does market surveys. The Rollum Sound Company hired Snoop to study the age distribution of people who stream music. To check the Snoop report, Rollum used a random sample of 519 customers and obtained the following data. Customer Age (yrs) Percent of Customers from Snoop Report Number of Customers from Sample Less than 14 12% 100 145 14 - 18 19 - 23 24 28 29 - 33 29% 11% 54 39 70 10% 14% More than 33 24% 111 A USE SALT Using a 1% level of significance, test the claim that the distribution of customer ages in the Snoop report agrees with that of the sample report. (a) What is the tevel of significance? 0.01 State the null and alternate hypotheses. O Ho: The distributions are the same. The distributions are the same. The distributions are the same. O Ho: The distributions are different. Ho: : The distributions are different. : The distributions are different. O Ho: The distributions are different. : The distributions are the same. (b) Find the value of the chi-square statistic for the sample. (Round the expected frequencies to at least three decimal places. Round the test statistic to three decimal places.) Are all the expected frequencies greater than 5? Yes O No What sampling distribution will you use? O Student'st chi-square iform
