Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

For the given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.) Insurance companies commonly use 10001000 miles as the mean number of miles a car is driven per month. One insurance company claims that the mean number of miles a car is driven per month is more than 10001000 miles. The insurance company conducts a hypothesis test and fails to reject the null hypothesis. Assume that in reality, the mean number of miles a car is driven per month is 12001200 miles. Was an error made? If so, what type?
