A study was conducted to determine the effects of two factors on the latherability of soap. The two factors were type of water (tap or distilled) and glycerol (present or absent). The outcome measured was the amount of foam produced (in milliliters). The experiment was repeated three times for each combination of the factors. The results are as follows. Make sure to include Test statistics and all 3 sets of hypothesis.

No Glycerol

Glycerol

Distilled Water

A study was conducted in a particular place,to determine the effects of vitamin A deficiency in preschool children.The investigators were particularly interested in whether children with vitamin A deficiency were at increased risk of developing respiratory infection,which normally causes death. 250 children were recruited in the study,and their age in years,gender(0=male,1=female),and whether they suffered vitamin A deficiency (0=no,1=yes) was recorded at an initial clinic visit (time 0).Also recorded was the response,whether the child was suffering from a respiratory infection (0=no,1=yes)....

Researchers conducted a study to determine the effects of different types of alcohol on the peak alcohol concentration. In one part of the study, the researchers gave 15 randomly select males a controlled volume of vodka and monitored the subjects' alcohol concentration following the period of consumption. The legal limit for driving is 80 mg/dL (milligrams per deciliter of blood). A hypothesis test was conducted to see if the mean peak alcohol concentration from drinking vodka was different from the...

Risk factors for obesity. A case control study was conducted to determine the risk factors associated with obesity in young adults. The study included 5,763 cases. Of the cases 62% ate fast food at least 3 times a week. It was a matched case control study and 2 controls were matched per 1 case. Of the controls 54% ate fast food at least 3 times a week. Using the above data and the analysis you provided, propose what should be...

A psychopharmacologist conducted a study on the effects of the drug lithium for the treatment of depression. Twenty-seven patients were chosen whose principal problem was depression. There were 3 groups: Placebo, Low Dose (50mg) and High Dose (200mg). There were 9 patients in each group. At the end of 30 days, the patients were evaluated for their level of depression, with higher scores indicating higher levels of depression.                 Fill in the blanks with the appropriate numbers, setting alpha=.05.

A study was conducted to determine if the salaries of elementary school teachers from two neighboring districts were equal. A sample of 15 teachers from each district was randomly selected. The mean from the first district was $28,900 with a standard deviation of $2300. The mean from the second district was $30,300 with a standard deviation of $2100. Assume the samples are random, independent, and come from populations that are normally distributed. Construct a 95% confidence interval for μ1 -...

A study was conducted to determine if the salaries of librarians from two neighboring states were equal. A sample of 100 librarians from each state was randomly selected. The mean from the first state was $29,100 with a standard deviation of $2,200. The mean from the second state was $31,900 with a standard deviation of $2,150. Test the hypothesis that there is no difference in the salaries from both states at the 0.1 significance level. determine the test statistic. Round...
