The tennessee tourism institute (tti) plans to sample information center visitors entering the state to learn the fraction of visitors who plan to camp in the state. current estimates are that 35% of visitors are campers. how many visitors would you sample to estimate the population proportion of campers with a 95% confidence level and an allowable error of 2%?

2185

Step-by-step explanation:

Let p be the proportion of visitors are campers.

Given : The Tennessee Tourism Institute (TTI) plans to sample information center visitors entering the state to learn the fraction of visitors who plan to camp in the state.

The prior proportion of visitors are campers : p=0.35

Allowable error : E= 2%= 0.02

We know that the z-value for 95% confidence =

Then by Central Limit Theorem , the required sample size would be :

Simply , we get

 [Rounded to the next whole number.]

Hence, the smallest sample size to estimate the population proportion of campers =2185

step-by-step explanation:

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
