Given two independent random samples with the following results:

n1=16 x‾1=128 s1=20   

n2=8 x‾2=99 s2=19

use this data to find the 90% confidence interval for the true difference between the population means. assume that the population variances are equal and that the two populations are normally distributed.

step 1 of 3: find the point estimate that should be used in constructing the confidence interval.

step 2 of 3: find the margin of error to be used in constructing the confidence interval. round your answer to six decimal places.

step 3 of 3: construct the 90% confidence interval. round your answers to the nearest whole number.

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.
