3.Zebra crossing is used by pedestrian to cross the road safely. However, there are few drivers_that ignore it (they do not stop even when they saw the pedestrian would like to cross theroad). A survey was conducted to identify which drivers (male or female) are moreaggressive drivers and are more prone to go through zebra crossing. A CCTV camera wasuse to record the behavior at various times of the day and monitored a random sample ofdrivers. The results are as follows: -MaleFemaleDrivers7153No of drivers going through zebra crossing5131Conduct a hypothesis test at the 5% level of significant to test the claim that male driversare more prone to go through zebra crossing compare to female drivers.

A large manufacturing company claims that less than 10% of its customers make a complaint about the company’s products. Test this claim at the 10% significance level, if a survey found that 29 out of a random sample of 320 of the company’s customers made a complaint about the company’s products.
A simple random sample of front-seat occupants involved in car crashes is obtained. AMoung 2747 occupants not wearing seatbealts, 37 were killed. Amoung 7682 occupents were wearing seatbelts, 11 were killed. Use significance level to test the claim that seat belts are effective in reducing fatalities. Consider the first sample to be the sample of occupents not wearing seat belts and the second sample to be the sample of occupants wearing seat belts. What are the null and alternative hypothesis for the hypothesis test?z= ?P Value= ??The appropriate confidence interval is= ?
A nationwide job recruiting firm wants to compare the annual incomes for childcare workers in New York and Illinois. Due to recent trends in the childcare industry, the firm suspects that the that the mean annual income of childcare workers in the state of New York is greater than the mean annual income of childcare workers in Illinois. To see if this is true, the firm selected a random sample of 20 childcare workers from New York and an independent random sample of 20 childcare workers from Illinois and asked them to report their mean annual income. The data obtained were as follows. Annual income in dollars New York 46686 , 34979 , 47325 , 48892 , 51128 , 56792 , 47785 , 48995 , 57301 , 55176 , 48002 , 45718 , 50351 , 58527 , 47067 , 53699 , 54361 , 49727 , 36426 , 50870 Illinois 48009 , 46871 , 42774 , 49790 , 43163 , 45401 , 41068 , 50300 , 47064 , 42003 , 47775 , 41917…
In a recent court case it was found that during a period of 11 years 888 people were selected for grand jury duty and 39% of them were from the same ethnicity. Among the people eligible for grand jury duty, 80.4% were of this ethnicity. Use a 0.01 significance level to test the claim that the selection process is biased against allowing this ethnicity to sit on the grand jury. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution.

The service manager of a car dealer wants to determine if owners of new cars (two years old or less) tune up their cars more frequently than owners of older cars (more than two years old). From his records he takes a random sample of ten new cars and ten older cars and determines the number of times the cars were tuned up in the last 12 months. The data follow. Do these data allow the service station owner to infer at the 10% significance level that new car owners tune up their cars more frequently than older car owners? Use the table to answer the following questions 2.What is the critical Value 3.What is the test statistic
A researcher is looking at the relationship between playing contact sports in high school and osteoarthritis among men in their forties. Among a random sample of 150 men between the ages of 40-49 who played contact sports in high school, 44 reported they had osteoarthritis in at least one knee. Among a random sample of 150 men aged 40-49 who did not play contact sports in high school, 16 reported having osteoarthritis in at least one knee. Does the proportion of men with osteoarthritis differ by whether they played contact sports in high school? Run the test at a 5% level of significance.

An insurance company is thinking about offering discounts on its life insurance policies to nonsmokers. As part of its analysis, the company randomly selects 200 men who are 60 years old and ask them if they smoke at least one pack of cigarettes per day and if they have ever suffered from heart disease. 10 out of the 38 smokers had suffered from some type of heart disease and 12 out of 150 nonsmokers had suffered from some type of heart disease. Can we conclude at the 5% level of significance that smokers have a higher incidence of heart disease than nonsmokers? (Don't hand writing solution)
In a certain school district, it was observed that 29% of the students in the element schools were classified as only children (no siblings).

Test at the α=0.05 level of significance.What is the hypothesized population proportion for this test?
