If you were constructing a 99% confidence interval of the population mean based on a sample of n 1) = 25 where the standard deviation of the sample S = 0.05, the critical value of t will be

We want a confidence of 99% so then the significance level would be 1%

The degrees of freedom are given by:

And the critical value using the significance level and and the critical value would be:

Step-by-step explanation:

We know the following info :

represent the standard deviation from the sample

represent the sample size selected

We want a confidence of 99% so then the significance level would be 1%

The degrees of freedom are given by:

And the critical value using the significance level and and the critical value would be:

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
