5.. solve all parts please
Use a 0.05 significance level to test the claim that peanut candies have weights that vary more than plain candies. The standard deviation for the weights of plain candies is
0.303. A sample of 81 peanut candies has weights with a standard deviation of 0.35. Assume the population is normally distributed.
(a) Write the claim mathematically and identify Ho and Ha
O A. Ho: os0.303; Hạ: o > 0.303 (Claim)
OB. Ho: o20.303 (Claim); H: o<0.303
OC. Ho: o= 0.303; H,: a # 0.303 (Claim)
(b) Find the critical value(s).
(Use a comma to separate answers as needed. Round to three decimal places as needed.)
Identify the rejection region(s).
OA.
OB.
Oc.
LA
(c) Use the y2-test to find the standardized test statistic,
(Round to three decimal places as needed.)
(d) Decide whether to reject or fail to reject the null hypothesis.
O Reject
O Fail to reject
(e) Interpret the decision in the context of the original claim.
Does it appear that peanut candies have weights that vary more than those of plain candies?
O A. Since the null hypothesis is rejected, the weights do not appear to vary
more for peanut candies.
O B. Since the null hypothesis is not rejected, the weights do not appear to vary
more for peanut candies.
OC. Since the null hypothesis is not rejected, the weights appear to vary more
for peanut candies.
O D. Since the null hypothesis is rejected, the weights appear to vary more for
peanut candies.
