In 2015, the sample mean of people spent reading was 2 hour. A researcher claims that this number has increased. He collects data from 10 random people for a week: 2 hr, 4 hr, 3 hr, 3.5 hr, 1 hr, .5 hr, 2.5 hr, 2 hr, 1.7 hr, 3 hr. Standard deviation=1, alpha=.05. Find z and p-value and determine if you should accept or reject the null hypothesis.
