An egg packing company has stated that the standard deviation of the weights of their grade A large eggs is 0.07 ounces or less. The sample variance for 51 eggs was 0.0065 ounces. Can this sample result confirm the company's claim? The test statistic is x^2 = 0.43. Find the p-value.

Answer #1

given data are:-

hypothesis:-

[ claim of the company ]

this is a right tailed test.

the test statistic is :-

df = (n-1) =(51-1) = 50

the p value is :-

[ in any blank cell of excel type =CHISQ.DIST.RT(0.43,50) ]

decision:-

p value = 1 > 0.05 (alpha)

we fail to reject the null hypothesis. there is enough sample evidence to confirm the company's claim.

*** if you have any doubt regarding the problem ,please write it in the comment box...if satisfied,please UPVOTE.

A random sample of 82 eighth grade students' scores on a national mathematics assessment test has a mean score of 292. This test result prompts a state school administrator to declare that the mean score for the state's eighth-graders on this exam is more than 285. Assume that the population standard deviation is 30. At α=0.14 is there enough evidence to support the administration's claim? Complete parts (a) through (e). a) Write the claim mathematically and identify H0 and Ha....

It has long been stated that the mean temperature of humans is 98.6 degrees F. ​However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6 degrees F. They measured the temperatures of 61 healthy adults 1 to 4 times daily for 3​ days, obtaining 275 measurements. The sample data resulted in a sample mean of 98.2 degrees F and a sample standard deviation of 1.1 degrees F. Use the​ P-value approach...
