In a sample of 200 books, 26 books contained at least one punctuation error. the sampling method had a margin of error of 0.03. what is the interval estimate for the proportion that would have at least one punctuation error in the form (lower limit, upper limit) ?

confidence interval =(0.10,0.16)

Step-by-step explanation:

Given that sample proportion was

26/200 =0.13 for a sample size of 200

Margin of error is given as 0.03

We know that confidence interval is one which is calculated as sample proportion ±Margin of error

Here sample proportion=0.13

Margin of error = 0.03

Hence

confidence interval lower limit = 0.13-0.03 = 0.10

Confidence interval upper limit = 0.13+0.03 = 0.16

Hence confidence interval =(0.10,0.16)

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
