A random sample of 88 eighth grade​ students' scores on a national mathematics assessment test has a mean score of 264. This test result prompts a state school administrator to declare that the mean score for the​ state's eighth graders on this exam is more than 260. Assume that the population standard deviation is 36. At α=0.02​, is there enough evidence to support the​ administrator's claim? Complete parts​ (a) through​ (e).

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6
