Hypothesis Testing. The researcher believes that if pregnant women take vitamins, the birth weight of their babies will be greater than 7.2 pounds. The researcher feeds vitamins to 49 pregnant women and measures the birth weights of their babies. The mean birth weight of the 49 babies born to women who take vitamins is 7.5 pounds, with a standard deviation of 0.9.

At alpha = .05, test the claim that the mean birth weight of babies whose mothers took vitamins is greater than 7.2 pounds.
Explain what a Type I Error would be for this experiment.
Explain what a Type II Error would be.

A researcher is testing the hypothesis that baby weight (in pounds) at 6 months after birth is related to breastfeeding (in oz). The regression equation is Weight = 6.5 + .48 * Milk/day. The Standard Error (SE) of the slope is 0.13, and the data were gathered from a sample of 320 babies (Alpha level is set at 0.05.) Which one of the following statements is INCORRECT? Hypothesis testing for a significant slope shows evidence that Milk/day is a statistically...

A hospital wishes to justify the benefits of nutrition programs for pregnant women using birth weight data from newborns. The hospital hopes to show that the mean birth weight for newborns from mothers who complete the program is higher than the birth weight for newborns from mothers who do not complete the program. A group of 12 pregnant women were randomly divided into two groups; the first group received the nutrition program and the second group did not receive the...

The weight gain of women during pregnancy has an important effect on the birth weight of their children. If the weight gain is not adequate, the infant is more likely to be small and will tend to be less healthy. In a study conducted in two countries, weight gains (in kilogram) of women during the third trimester of pregnancy were measured. The results are summarized in the following table. Country n ȳ s2 Egypt 6 3.8 5.76 Kenya 10 3.3...

A medical researcher is interested in the prenatal care received by pregnant women in inner cities. She interviews 20 randomly selected women with children on the streets of Baltimore and finds that the average number of gynecological check ups per pregnancy was 4, with a standard deviation of 1. Using a 95% level of confidence, estimate the population mean number of gynecological visits per pregnancy. Write a concluding statement. An educational researcher sought to estimate the average number of close...

Research on the relationship between the participants’ depression score and weight. The researcher believes that a person’s weight may affect their level of depression. Create a simple linear regression model (including the y-intercept), where depression score is the dependent variable and weight is the independent variable. Use your simple linear regression model to answer the following questions with α = 0.05. Predict the depression score for a person that weighs 185 lbs. Estimate the average depression score for people that...

A researcher believes that women today weigh less than in previous years. To investigate this belief, she randomly samples 15 adult women and records their weights. The scores have a mean of 111 lbs. and a standard deviation of 13.4. A local census taken several years ago shows the mean weight of adult women was 120 lbs. What would you conclude using α =0.011tail? Make sure to indicate your hypotheses, your critical value, your decision, and your conclusion. 1. What...

Birth weight and gestational age. The Child Health and Development Studies considered pregnancies among women in the San Francisco East Bay area. Researchers took a random sample of 50 pregnancies and used statistical software to construct a linear regression model to predict a baby's birth weight in ounces using the gestation age (the number of days the mother was pregnant). A portion of the computer output and the scatter plot is shown below. Round all calculated results to four decimal places....
