3. You were asked to investigate the association between smoking among mothers and infant low birth weight. You were asked to calculate a measure of association like an Odds Ratio together with the confidence intervals. They asked you to calculate a 90% confidence interval instead of a 95% confidence interval.

Will the lowering of the confidence interval from 95% to 90% increase or decrease the chance of making Type 1 error?

Will this affect the probability of making Type 2 error?

How will this affect the power of the study? Explain your answer.

Medical researchers are concerned about the association between maternal smoking habits and the need for caesarian section during birth. Suppose the researchers gather 423 expecting mothers in their third trimester and follow them through pregnancy to examine the incidence of caesarian. Suppose out of the 102 mothers that reported smoking cigarettes at least once during pregnancy, 59 of them were referenced to have needed caesarian intervention during delivery, while 73 of the mothers with no smoking history reportedly needed the...

Question 4: I was 0 when I was born. How old were you, Mom? Students in a different statistics class were asked to report the age of their mothers when they were born. Here are the summary statistics: Sample size: 28 sample mean: 29.643 years sample stDev: 4.564 years a. Calculate the standard error of this sample mean. b. Determine and interpret a 90% confidence interval for the mother’s mean age (at student’s birth) in the population of all students...

A random sample of 1200 Freshmen at UGA were asked if they had applied for student football tickets. The proportion who answered yes was 0.86. The standard error of this estimate is 0.010. (a) Find the margin of error for a 95% confidence interval for the population proportion who applied for football tickets. (3 decimal places) (b) Construct the 95% confidence interval. Lower Limit (3 decimal places) Upper Limit (3 decimal places) (c) Since the sample was randomly selected, will...

Pregnant women were recruited during their first trimester to study the relationship between chocolate consumption during pregnancy and risk of preeclampsia (pregnancy-induced hypertension). They were interviewed about chocolate consumption, age, race, education, smoking, body mass index, and previous pregnancy history. Participants were re-interviewed after delivery to obtain information on chocolate consumption during the third trimester of pregnancy. In addition, umbilical cord blood was collected at the time of delivery and measured for concentration of theobromine (the major metabolite of chocolate)....

1.The sample mean is an unbiased estimator for the population mean. This means: The sample mean always equals the population mean. The average sample mean, over all possible samples, equals the population mean. The sample mean will only vary a little from the population mean. The sample mean has a normal distribution. 2.Which of the following statements is CORRECTabout the sampling distribution of the sample mean: The standard error of the sample mean will decrease as the sample size increases....

T-tests are used when you want to examine differences but you do not know everything about the population. There are three types of t-tests that you may choose to do: one-sample t-test, independent sample t-test, or dependent sample t-test. You can calculate these by hand, in SPSS, or in Excel. The instructions below can be used for SPSS and your textbook offers instructions for using Excel. Single-sample t-tests These tests are used when you want to determine the probability that...

1. A city official claims that the proportion of all commuters who are in favor of an expanded public transportation system is 50%. A newspaper conducts a survey to determine whether this proportion is different from 50%. Out of 225 randomly chosen commuters, the survey finds that 90 of them reply yes when asked if they support an expanded public transportation system. Test the official’s claim at α = 0.05. 2. A survey of 225 randomly chosen commuters are asked...
