1- Find the upper limit of the 99% confidence interval for the mean weight of the adult male Eastern American Toad population ux to the nearest

thousandth (at least 3 decimal places).

2- Find the lower limit of the 95% confidence interval for the mean weight of the adult male Eastern American Toad population to the nearest thousandth (at least 3 decimal places).

QUESTION 3

Let x be the random variable that measures the weight of an adult male Eastern American Toad. In a sample of 81 adult male Eastern American Toads the mean weight x was 26 g with a standard deviation Sx of 4 g.

Using this data find the upper limit of the 95% confidence interval for the mean weight μ population to the nearest thousandth (3 decimal places).

of all adult male Eastern American Toads in the population to the nearest thousandth

4- Find the lower limit of the 95% confidence interval for the mean weight of the adult male Eastern American Toad population ux to the nearestthousandth (at least 3 decimal places).

5- With respect to calculating the 99% confidence interval for the mean weight of the adult male Eastern American Toad population ux find the margin of error MOE to at least 4 decimal places of accuracy.
