A university department administers a survey, regarding student satisfaction. Based on the survey results, the department provides a confidence interval

estimate of 60% to 80% for student satisfaction. If the department wishes to

construct a confidence interval that more accurately represents the

proportion of student satisfaction, how should the design be altered?

A. Use a smaller confidence level

B. Use a smaller sample size

C. Use a larger confidence level

D. Use a larger sample size

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
