She interviews 34 randomly selected people who train in groups, and finds that they run a mean of 44.2 miles per week. Assume that the population standard deviation for group runners is known to be 2.5 miles per week. She also interviews a random sample of 49 people who train on their own and finds that they run a mean of 45.1 miles per week. Assume that the population standard deviation for people who run by themselves is 1.1 miles per week. Test the claim at the 0.01 level of significance. Let group runners training for marathons be Population 1 and let individual runners training for marathons be Population 2. Required:
Compute the value of the test statistic.

Play us like pawns and relentlessly confine,
Into living up to gender roles and having absent minds
Don't you think it's funny how they tell us how to live?
Don't you think it's funny how we're all delinquent kids?
Like, hush now, don't say, don't say

Hush, boy, oh, hush, boy, don't say a word
Throw on a jersey and no one gets hurt
Hush, girl, oh, hush, girl, just bat your eyes
Play our little game, play our little game

Bounded all thoughts and corrected common sense
You're raising suicidals with your predetermined titles
Like "a mess", "distressed", "I am unimpressed", "you're excess",
"a dress is all you'll ever be".
Gender roles impose control and deceive progressive times
Welcome to the land of the broken minds
