In a particular year in your health jurisdiction, there were 1000 births. In reviewing their birth certificates, you found that 72 had low birthweights (<2500 gms), and 158 had mothers who smoked during pregnancy. Of the mothers who smoked during pregnancy, you found that 19 had low birth weight babies .Show calculations To explore the relationship between maternal smoking and the occurrence of low birth weight, construct the following a 2 x 2 contingency table. What are the relative risks for each of the two sets of mothers? What is the relative risk ratio?

A marketing manager of a pizza parlor propose a campaign to promote online sales in a town during the time of lockdown. It is proposed that customers be compensated with RM7 e-Voucher if delivery time is greater than 20 minutes for addresses located within four kilometers radius from the parlor with minimum order of RM40. The manager collected delivery time of 30 orders out of the total of 180 orders in the month of January of 2021 and found that the delivery time has mean of 15 minutes. In the past, the standard deviation of delivery time for the delivery staff has been found 3 minutes. What is the probability that delivery time within the town is less than 10 minutes?

Suppose a sample of 16 light trucks is randomly selected off the assembly line. The trucks are driven 1000 miles and the fuel mileage (MPG) of each truck is recorded. It is found that the mean MPG is 22 with a SD equal to 3. The previous model of the light truck got 20 MPG. Conduct a one-sample t-test using the seven-step process and with this information, what can you conclude in step 6? Group of answer choices a. Fail to reject H0 b. Not enough information to make a decision c. Reject H0 d. The one-sample t-test is not the correct test
A 7th grade science teacher would like to know if spending more time doing class experiments will help his students preform better on tests. In a day, he teaches 4 periods of science, so for his 1st and 3rd period classes, he taught as he normally does with mostly lectures and occassional class experiments. For his 2nd and 4th period classes, he did a class experiment everyday with minimal lectures. There were n=25 different students in each of his classes. He then wanted to compare the exam averages between his classes to see if student preformance was significantly different. Which statistical tests should he use?

Workers at a particular mining site receive an average of 35 days paid vacation, which is lower than the national average. The manager of this plant is under pressure from a local union to increase the amount of paid time off. However, he does not want to give more days off to the workers because that would be costly. Instead he decides he should fire 10 employees in such a way as to raise the average number of days off that are reported by his employees. In order to achieve this goal, should he fire employees who have the most number of days off, least number of days off, or those who have about the average number of days off? a. He should fire employees who have the most number of days off. b. No matter who he fires, it will not increase the amount of paid time off. c. He should fire employees who have the average number of days off. d. He should fire employees who have the least number of days off.
Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x=99.69, y=101.15, r=0.903, P-value=0.000, and y=−0.2+1.02x, where x represents the IQ score of the twin born second. Find the best predicted value of y given that the twin born second has an IQ of 108? Use a significance level of 0.05. The best predicted value of Y is?
