PLEASE IGNORE REPEATED MESSAGES, I AM JUST PASTING ALL I GOT REPEATEDLY

Where are the calculations for Confidence intervals of question 1 point 2 c)? You didn't include those in the excel. And how did you get the £ amount in that later question? I understand you multiply the confidence interval value by 1000. E.g. in first case M=25, you multiply .3064 by 1000 and get 306.4. But then why do you write £ 3064 instead of £ 306.4? In question 2 i) you didn't mention how Sarah should answer the question In question 2 ii) you didn't complete the final sentence. It's not clear what Sarah should do. You wrote "...So Sarah has to test whether store performance and tenure." That's neither a complete nor logical sentence

First of all, questions 2 i) and ii) are in the Word document only and are not calculation questions. You simply didn't make sense as the questions were not answered completely. 2 i) you didn't mention how Sarah should answer the question n question 2 ii) you didn't complete the final sentence. It's not clear what Sarah should do. So please complete the actual sentences. Regarding the excel, the calculations for Confidence intervals of question 1 point 2 c) are not in excel. And how did you get the £ amount in question 2 c)??? I understand you multiply the confidence interval value by 1000. E.g. in first case M=25, you multiply .3064 by 1000 and get 306.4. But then why do you write £ 3064 instead of £ 306.4?

In question 1 point 2 i) you didn't answer the part on how Sarah has to answer the question....It's simply missing. In question 1 point 2 ii) you wrote "...So Sarah has to test whether store performance and tenure." THIS IS NOT A COMPLETE AND LOGICAL ENGLISH SENTENCE!!!!!!!! did you want to say "So Sarah has to test whether store performance and tenure are related" ???
