Section 1: One Sample Hypothesis Testing Research Question: Is average January snowfall rate
significantly greater than 53cm ? The Excel spreadsheet entitled "Ottawa_Snowv2.xls" lists the
monthly snowfall for each month from 1890 to 2001 . The first column is the year; the second
column is the snowfall amounts for September; the third column for October and so on. - Open the
monthly snowfall data in Excel. - Open the spreadsheet called "Assignment_4 hypothesis
tests.xIs". Make sure to select the worksheet entitled 'One-Sample'. - Copy the relevarit monthly
data from the Ottawa_Snowv2 spreadsheet to the Assignment_4 hypothesis test spreadsheet.
The data needs to be pasted in column D (red). - In the grey boxes, enter the degrees of freedom
and hypothesized mean, or the population mean you are comparing to the monthly snowfall (this
will come from the research question). For the hypothesis test results, answer the following.
Question 1: i. state your null hypothesis and alternative hypothesis. Be specific and do not use
generic forms in your answer. (1 mark) ii. specify your significance level and critical statistic (you
can get this value from a table) (1 mark) iii. include the test results from Excel (cut the output from
Excel and paste it into Word). Only include the statistics. ( 1 mark) iv. state whether the null
hypothesis should be rejected or accepted based on p-value and explain why (2 marks). Make
sure to state the p-value and test value ( Z-statistic or T-statistic) in your answer. v. finally, what is
your answer regarding the research question (2 marks)4.0 20 0.0
