Question

Use the folloving to ansver questions 16 and 17 A study of rural literacy in boys age 10-15 in Mali found with 95% confidence that the true proportion of rural boys that are literate is between 0.51 and 0.57. 15. Which of the following are true statements about this confidence interval? A. We don't know exactly what proportion of rural Malinese boys, age 10-15, are literate, but the interval from 0.51 to 0.57 contains the true proportion. B. We know that the proportion of Malinese boys, age 10-15, that are literate is between 0.51 and 0.57. C. We are 95% confident that between 51% and 57% of rural Malinese boys, age 10-15, are literate. D. Between 51% and 57% of rural Malinese boys, age 10-15, are literate. 16. What are the point estimate of the true proportion AND the margin of error for the proportion of rural Malinese boys who are literate?

Explanation / Answer

Q15) Option A is Correct. We don't know exactly what proportion of rural Malinese boys , age 10-15 are literate but the interval from 0.51 to 0.57 contain true proportion

Q16) Let Point estimate be a

Margin of error be b

Then

a-b = 0.51

a+b = 0.57

a = 0.54 and b = 0.03

So, Point estimate be 0.54 and Margin of error be 0.03
