Answer:

Equal to the difference between median and 75th percentile.

Step-by-step explanation:

xth percentile:

If a measure is said to be in the xth percentile, it means that x% of the measures are smaller than it, and (100-x)% are larger.

Distance between percentiles:

If the difference between two percentiles is the same, the difference between the measures should also be the same.

Median:

The 50th percentile is called median.

In this question:

75th percentile - 50th percentile = 25

50th percentile - 25th percentile = 25

The differences should be equal.

Complete Question

In a random sample of 13 microwave ovens, the mean repair cost was $90.00 and the standard deviation was $15.20. Using the standard normal distribution with the appropriate calculations for a standard deviation that is known, assume the population is normally distributed, find the margin of error and construct a 98% confidence interval for the population mean u. A 98% confidence interval using the t-distribution was (78.7,101.3). Compare the results. The margin of error of u is
