A random sample of 25 married persons found that they spend on average 2.6 hours a day on their phone, with a standard deviation of 0.58. A random sample of 20 single persons found that they spend on average 3.08 hours per day on their phone, with a standard deviation of 0.42. Test to see if single people spend significantly more time on their phones than married people do. Test the claim using a 5% level of significance. Assume the population standard deviations are unequal and the populations are normally distributed. Use Group 1 = Married, Group 2 = Unmarried.

Use z-scores to make the following comparison. A high school student took two college entrance exams, scoring 1110 on the SAT and 27 on the ACT. Suppose that SAT scores have a mean of 950 and a standard deviation of 130 while the ACT scores have a mean of 22 and a standard deviation of 4. Assuming the performance on both tests follows a normal distribution, determine which test the student did better on.
A sleeping pill company have a pill that they claim will help you fall asleep in less than 30 minutes. A researcher is very skeptical of this claim and believe that it is more than 30 minutes.
