Answer #1

The answer is -FALSE.

EXPLANATION:

In Minitab,R or in other statistical softwares,we can find the confidence interval for the difference between the population proportions just by using the sample estimates of the population proportions under consideration.(So,we can find the required confidence interval just by using the appropriate codes).

On the other hand,when we use EXCEL for the same purpose,we need to find the critical value,margin of error,lower and upper bounds of confidence intervals separately using the usual formulae,which is not as easy as to find the confidence interval using Minitab or other statistical softwares.

Hence,the given statement is -False.(ANSWER)
