Out of the 30 boys, only 9 answered "yes" while out of the 45 girls,39 said that they are willing to write to their mother on Mother's Day.

Fear of the dark is quite common among children. However, what about adults? One polling agency released the results of a survey that asked people over 30 years old if they keep the lights on at night. Among 452 respondents, 34% indeed leave the light on when going to sleep. What does this margin of error tell you about the percentage of adults who keep the lights on at night? We can be 95% confident that somewhere between % and % of adults keep the lights on at night.
UCLA conducted a survey of more than 263,000 college freshmen from 385 colleges in fall 2005. The results of students' expected majors by gender were reported in The Chronicle of Higher Education (2/2/2006). Suppose a survey of 5,000 graduating females and 5,000 graduating males was done as a follow-up last year to determine what their actual majors were. The results for males are shown in the table below. The second column in the table does not add to 100% because of rounding.Conduct a goodness-of-fit test to determine if the actual college majors of graduating males fit the distribution of their expected majors.

Some sleep experts believe that sleep apnea is more in men than in the general population. In other words, they claim that the percentage of men who suffer from sleep apnea is greater than 8% (which is the percent believed to affect the population in general). To test this claim, one sleep expert interviews 50 men and determines that 7 of these men suffer from sleep apnea. Does this evidence support the claim at that the percentage of men who suffer from sleep apnea is more than 8%? Use a 0.02 level of significance What are the hypotheses? What is the test statistic? Is it a z or a t? Find the P-value for this test statistic. How does it compare to the significance level? On the normal curve, indicate the location of the test statistic and the p-value. (label them on the graph) Write a conclusion in statistical terms and relate it to the parameters of this problem. Note: The following is not a hypothesis test, but rather a…
