You are testing the claim that having lights on at night increases weight gain (abstract). A sample 10 mice lived in an environment with bright light on all of the time and 8 mice who lived in an environment with a normal light/dark cycle is given below. Test the claim using a 10% level of significance. Assume the population variances are unequal and that the weight changes are normally distributed. Give answers to 3 decimal places.

You are testing the claim that having lights on at night increases weight gain (abstract). A sample of
10 mice lived in an environment with bright light on all of the time and 8 mice who lived in an
environment with a normal light/dark cycle is given below. Test the claim using a 10% level of
significance. Assume the population variances are unequal and that the weight changes are
normally distributed. Give answers to 3 decimal places.
