Arecent gallup poll asked 1006 americans, "during the past year, about how many books, either hardcover or paperback, did you read either all or part of the way through? " results of the survey indicated that x = 13.4 books and s = 16.6 books. construct a 99% confidence interval for the mean number of books americans read either all or part of during the preceding year. interpret that interval.

The required interval is

Step-by-step explanation:

Consider the provided information.

It is given that:

n = 1006, mean = 13.4 and s = 16.6  

We need to construct a 99% confidence interval.

That means α = 0.01 and α/2 = 0.005

First find the standard error as shown:

Now to calculate confidence interval calculate:

Hence, the required interval is

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
