Question
When 45 people used a certain diet for one year, their weight losses had a standard deviation of 4.8 lb. Use a 0.10 significance level to test the claim that the amounts of weight loss have a standard deviation equal to 5.5 lb, which appears to be
the standard deviation for the amounts of weight loss with a different diet. Assume that a simple random sample is selected from a normally distributed population.
What are the correct hypotheses for this test?
Họ: 0
Ib
H;: o
V Ib
Calculate the value of the test statistic.
(Round to two decimal places as needed.)
Use technology to determine the P-value for the test statistic.
The P-value is
(Round to three decimal places as needed.)
What is the conclusion at the 0.10 level of significance?
Since the P-value is
the level of significance,
the null hypothesis. There
sufficient evidence to conclude that the sample is from a population with a standard deviation not equal to
Ib.
