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
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The sample is
The sample mean is
The standard deviation is
The lower limit of the 98% confidence interval is
The upper limit of the 98% confidence interval is
Generally the margin of error is mathematically represented as
=>
=>
