  • all the population of the country

b. Identify the sample for the study.

  • 50 adults (the ones that were surveyed)

c. Identify the parameter of interest in the study.

  • the parameter of interest is the people that believe that coffee shops are overpriced

d. Find and interpret a 95​% confidence interval for the parameter of interest.

z score for a 95% confidence level = 1.96

margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579

95% confidence level interval:

0.4 - 0.13579 = 0.26421

0.4 + 0.13579 = 0.53579

  • 95% confidence interval (0.26421 , 0.53579)

goblinko [34]
First off we need to find the denomonator:
11+37+83+19=150

Okay so our probability of getting a small size of a t-shirt will be 11/150
They sold 45,000
That's where we need to change our denominator to get how many shirts were small

45,000÷150=300
300×11=3,300
I multiplied 11 because of the numerator

So our answer is B. 3300
