You are conducting a study to better understand the average number of times per week that Michiganders have been going grocery shopping during stay-at-home order in the month of May 2020. Assume that the standard deviation of shopping trips per week is 2.5 trips. Before you begin the study, you need to find the necessary sample size in order to have 95% confidence in your population estimates, with a margin of error of 1 trip or less. The number of Michiganders who should be sampled, given a this level of confidence and margin of error is

Suppose that you need to have 99% confidence in your population estimates, and you still need a margin of error of 1 trip or less. The number of Michiganders who should be sampled, given this level of confidence and margin of error is

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

60

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
