Part 1

What is the lower limit of this confidence interval?

Write the answer as a number with at least four decimals.

Part 2.

Based on the sample data that you are given, calculate the prediction interval at a

90% confidence level.

What is the upper limit of this prediction interval?

Write the answer as a number with at least four decimals.

What is the lower limit of this prediction interval?

Write the answer as a number with at least four decimals.

Part 3.

The management is curious to know whether the premium branding in India worked

or not. They want you to test if the weekly sales per customer at the Indian coffee

shops is greater than their global weekly sales per customer with a confidence level

the following hypothesis test:

H 0 : Average weekly sales in India are not greater than the population mean at a

confidence level of 99%

H 1 : Average weekly sales in India are greater than the population mean at a

confidence level of 99%

Reject H0: You are 99% confident that the MoonDoe coffee shops in India have

sales greater than population mean. correct

Fail to Reject H0: You are not 99% confident that the MoonDoe coffee shops in India

have sales greater than population mean.

Accept H0: Sales from MoonDoe cafe in India are not greater than the population

mean at the 99% confidence level.

What is the p-value for this hypothesis test ?
