Life-saving drug: Penicillin is produced by the Penicillin fungus, which is grown in a broth whose sugar content must be carefully controlled. Several samples of broth were taken on three successive days, and the amount of dissolved sugars, in milligrams per milliliter, was measured on each sample. The results were as follows. Day 1: 5.2 5.0 5.4 5.2 5.3 5.0 4.9 5.0 5.2 5.0 4.6 5.3 Day 2: 5.6 4.8 4.9 5.3 5.2 4.9 5.4 5.0 5.4 4.9 5.5 5.4 Day 3: 5.9 4.9 5.3 5.4 5.2 5.5 5.0 5.8 5.5 5.4 5.4 5.1 Construct an ANOVA table.

From the attached file we will conduct a hyothesis test to determine whether oxidation thickness is linearly related to tempertature. Assume significance is alpha 0.05. Null hypothesis = 0 Alternative hypothsis does not equal 0 a. employ the t-test statistic and name the sampling distribution of the test statistic. b.Should we reject the null and justify? C. use p-value to and draw the sampling distribution and shade area corresponding to p-value
A researcher conducts a two-year study comparing the number of cavities in a group of 30 randomly selected young children from the community before and after the application of fluoride to test if there is a decrease in the number of cavities.

Mercury Levels in Fish Figure 4.25 shows a scatterplot of the acidity (pH) for a sample of n = 53 Florida lakes vs the average mercury level (ppm) found in fish taken from each lake. The full dataset is introduced in Data 2.4 and is available in FloridaLakes. There appears to be a negative trend in the scatterplot, and we wish to test whether there is significant evidence of a negative association between pH and mercury levels. Figure 4.25 Water pH vs mercury levels of fish in Florida lakes (a) What are the null and alternative hypotheses? b) For these data, a statistical software package produces the following output: r=−0.575p-value=0.000017 Use the p-value to give the conclusion of the test. Include an assessment of the strength of the evidence and state your result in terms of rejecting or failing to reject H0 and in terms of pH and mercury. (c) Is this convincing evidence that low pH causes the average mercury level in fish to increase? Why or why not?
