The confidence interval also has a very high range of values and so it means that the proportion can be between 30% to 58% of the customers.
The manager’s speculation that the average number of years lived in the current home is less than 13 years does not seem to be correct. The mean number of years lived in the current home is around 12.26 years.

The null hypothesis was rejected as the test statistic was higher than z-value during the hypotheses testing. It shows that urban customers also have a high amount of credit against their name and we can be 95% confident that on average an urban customer’s credit amount would lie between $4299.65 and $5051.02.

The sampling distribution of the sample mean of credit customers will be approximately normal regardless of the distribution of individual credit customers.
The confidence interval level is (0.30, 0.58). It means that we are 95% confident that population proportion of customers who live in urban area lie between the lower and the upper limit of the ...Download file to see next pagesRead More
