Answer:5

Step-by-step explanation:

Given

Rachel sold twice as many books on tuesday as she did on monday

and on Wednesday she sold 6 fewer books than she did on tuesday during three days .

Let books sold on Monday is x

therefore on tuesday it is 2x

on wednesday it is 2x-6

And Rachel sold a total of 19 books '

therefore

x+2x+2x-6=19

5x=25

x=5

Therefore she sold 5 books on Monday

M + t + w = 19
t = 2m
w = 2m - 6

now we sub
m + (2m) + (2m - 6) = 19...combine like terms
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25/5
m = 5 <== she sold 5 books on Monday

t = 2m......t = 2(5)...t = 10 <== she sold 10 books on Tuesday
w = 2m - 6....w = 2(5) - 6....w = 10 - 6...w = 4 <== she sold 4 books on Wednesday.

Answer:

They can either decrease the confidence level or increase the sample size, that is, survey more students.

Step-by-step explanation:

The width of a confidence interval is given by:

M = z*\frac{\sigma}{\sqrt{n}}

In which z is the critical value correponding to the confidence level(higher confidence level, higher z is), \sigma is the standard deviation of the population and n is the size of the sample.

The students realize that this interval contains a large margin of error. What can they do to make a narrower interval?

Looking at the formula for M, they can either decrease the confidence level or increase the sample size, that is, survey more students.
