Question

The mean rate for satellite television from a sample of households was $49.50 per month with a standard deviation of $2.75. Estimate the percentage of satellite television rates between $45 and $55 per month using a confidence interval.

Answer 1

To estimate the percentage of satellite television rates between $45 and $55 per month using a confidence interval, we need to calculate the standard error, which is not possible with the given information.

Step-by-step explanation:

To estimate the percentage of satellite television rates between $45 and $55 per month using a confidence interval, we can use the normal distribution and the given mean and standard deviation.

First, we need to calculate the standard error, which is the standard deviation divided by the square root of the sample size. Since the sample size is not provided, we cannot calculate the standard error and cannot proceed with the estimation.

Therefore, we cannot estimate the percentage of satellite television rates between $45 and $55 per month using a confidence interval based on the given information.
