Among 20 golden hamster litters recorded, there was a sample mean of =7.72 baby hamsters, with a sample standard deviation of s=2.5 hamsters per liter. Create a 98% confidence interval for the mean number of baby hamsters per liter.

Step-by-step explanation:

For this case we have the following info given:

represent the sample mean

represent the sample deviation

represent the sample size

The confidence interval is given by:

The confidence interval is 98% and the significance level is the degrees of freedom are given by:

And the critical value would be:

And replacing we got:

do i do it on a graph?

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
