Question(14): A researcher wanted to know whether children who live in two different neighbourhood (Willowdale and Forresthill) got different amount of excerise. Children were randomly selected from the two neighbourhoods (40 in each). and filled out the daily activity report to measure their excerise. The number of minutes of excerise were tallied and recorded. The The researcher then conducted an independent sample t test using MS-EXCELL. The result are shown in the image below. Inspect the MS- EXCELL output.Did the researcher conduct their t test assuming equal variance.? Write out Step 5 by including both the formal answer and the conclusion. The five steps are: Step 1:State the hypotheses and identify the claim. Step 2: Compute the test value Step 3: Compute the critical value. Step 4:Make the decision (reject or not reject) Step 5:Summaize the results. Note: you only need to submit step 5, and round snswer to decimal places MS-EXCELL output: Willowdale Forresthill mean 108.65 86.93 variance 2601.67 1238.99 observations 40 40 pooled variance 1920.13 hypothisized mean difference 0 df 78 t stat 2.22 P(T<=t)(one tail) .01 t critical value(one tail) 1.66 P(T<=t)(two tail ) .03 t critical value (two tail) 1.99

A researcher wanted to know whether children who live in two different neighbourhood (Willowdale
and Forresthill) got different amount of excerise. Children were randomly selected from the two
