Researchers were interested in comparing students at private universities and students at public universities with respect to how much time they spent working in a typical week. They e-mailed a survey to 1000 students enrolled at a particular private university and to 2000 students enrolled at a particular public university. Data from the 200 private university students who responded to the survey and the 900 public university students who responded to the survey were used to see if there was a significant difference in the mean number of hours worked in a typical week. Which of the following does NOT limit the researchers’ ability to generalize to the two populations of interest?

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
