Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 21 cans of the soda drink. Those volumes have a mean of 12.19 oz and a standard deviation of 0.14 oz, and they appear to be from a normally distributed population. Use the sample data to test the claim that the population of volumes has a standard deviation less than 0.15 oz. Use a 0.01 significance level. Complete parts (a) through (d) below. a. Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: o20.15 oz H: o<0.15 oz O B. Ho: o>0.15 oz H,: o =0.15 oz O C. Ho: o=0.15 oz H: a<0.15 oz O D. Ho: o= 0.15 oz H: o 0.15 oz b. Compute the test statistic. (Round to three decimal places as needed.) c. Find the P-value. P-value = (Round to four decimal places as needed.)

![Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 21 cans of the soda
drink. Those volumes have a mean of 12.19 oz and a standard deviation of 0.14 oz, and they appear to be from a normally distributed
population.
Use the sample data to test the claim that the population of volumes has a standard deviation less than 0.15 oz. Use a 0.01 significance
level. Complete parts (a) through (d) below.
a. Identify the null and alternative hypotheses. Choose the correct answer below.
O A. Ho: o0.15 oz
H,: o<0.15 oz
O B. Ho: o>0.15 oz
H:o=0.15 oz
O C. Ho: o=0.15 oz
H,: o<0.15 oz
O D. Ho: o =0.15 oz
H:o#0.15 oz
b. Compute the test statistic.
x² = ]
(Round to three decimal places as needed.)
c. Find the P-value.
P-value=
(Round to four decimal places as needed.)
