In a random sample of six microwave ovens, the mean repair cost was $80.00 and the standard deviation was $11.00. assume the population is normally distributed and use a t-distribution to construct a 90% confidence interval for the population mean mμ. what is the margin of error of mμ? interpret the results.

E=14.1641

Step-by-step explanation:

We have given that

Assuming a confidence interval of 95% for \mu we have that,

Where is Margin of error given by,

For 95% in the T-Table we have that , so

So our Margin of error (E) is 14.1641

step-by-step explanation:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
