pe question
assume that you have a sample of n with the sample mean x, 41, and a sample standard deviation of s, -4, and you have an independent sample of my from another population with a sample mean of
x2 - 36, and the sample standard deviation s2 8. construct a 99% confidence interval estimate of the population mean difference between and 12. assume that the two population variances are equal

the answer is 45 i just did it on oddesy ware

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

answer: 88
