Suppose you are planning to sample cat owners to determine the average number of cans of cat food they purchase monthly. the following standards have been set: a confidence level of 99 percent and an error of less than 5 units. past research has indicated that the standard deviation should be 6 units. what is the final sample required? if only 30 percent of households have a cat, what is the initial number of households that need to be contacted?

Given : Significance level :

Critical value :

Margin of error :

Standard deviation :

The formula to find the sample size :-

Then, the sample size will be :-

The minimum final size sample required is 10.

If only 30 percent of households have a cat, then the proportion of households have a cat = 0.3

The formula to find the sample size :-

Then, the sample size will be :-

Hence, the initial number of households that need to be contacted =1
