Answer #1

First we need to find the mean and SD of data. Following table shows the calculation:

Sample size n =24 Sample sum: Er-1584 Sample mean: Σx =1584/24 п -66 Sample standard deviation: Σ (r-) =sqrt(3676/(24-1). п-1

--------------------------------------------------

Hypotheses are: Ho u 60 Ha u60 Level of significance: a 0.01 Test is one tailed (right tailed). Degree of freedom df =n-1-23

Conclusion: There is evidence to support the group's claim.
