2. Population Means - Independent Samples
Nightingale shoes is interested to know who is spending more on their brand: women or men. They surveyed the first 200 people
who entered their store. They found that 89 men on average spent $65 with a standard deviation of $6. On the other hand, 111
women spent $72 with a standard deviation of $23. Test the claim that women spend more on Nightingale shoes then men.
Assume a 0.05 significance level and the population standard deviations are unknown.
