DIASTOLIC BLOOD PRESSURE Listed below are diastolic blood pressure measurements (mm Hg) of females selected from Data Set 1 “Body Data” in Appendix B. All of the values are even numbers. Are there any outliers? If so, identify their values.
The director of a shipping company believes that there is a relationship between the cost of a customer’s shipment (£) and the weight (lb) of the package being shipped. For investigating this possible relationship, a random sample of nine customer shipments was selected and the weight (in lb) and the cost (rounded to the nearest £) for each shipment were recorded. The results obtained are shown in the table below (on the picture). required: a) ) The scatter diagram showing the relationship between the cost of acustomer’s shipment (£) and the weight (lb) of the package being shipped, is given below. Comment fully and clearly on this diagram. i) ii)

Plot and describe the distribution of HAV angles among young patients needing surgery for this condition. Provide an appropriate numerical summary. If there are outliers, also obtain the summary statistics omitting them and discuss their influence. Plot and describe the distribution of MA angles among young patients needing surgery for this condition. Provide an appropriate numerical summary. If there are outliers, also obtain the summary statistics omitting them and discuss their influence. Doctors speculate that the severity of MA can help predict the severity of HAV. Make a scatterplot of the data and describe the relationship between MA angle and HAV angle, including any possible outliers. If appropriate, obtain the equation of the least-squares regression line for predicting HAV angle from MA angle. Do the data appear to support the doctors’ speculation? If so, how good a predictor would MA angle be? Provide a numerical measure to support your conclusion.

Relatively minor repetitive impacts to the head such as those experienced by elite male soccer players when hit-ting a soccer ball with their heads may cause brain dam-age, according to the Journal of the American Medical Association. One indicator of mild brain injury is calledradial diffusivity. The radial diffusivity measurements oftwelve right-handed male soccer players were comparedto those of eleven competitive swimmers (who are notlikely to have repeated head impacts). Which type of plotwould not be appropriate for assessing the differencebetween the two groups?A) Stacked dotplots, one for each group, on the sameaxisB) Side-by-side boxplotsC) Stacked bar graphsD) A back-to-back stem-and-leaf plotE) A pair of histograms, one above the other, on the sameaxis. www.medpagetoday.com/Neurology
In a study, researchers wanted to measure the effect of alcohol on the hippocampal region, the portion of the brain responsible for long-term memory storage, in adolescents. The researchers randomly selected 21 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02cm3. An analysis of the sample data revealed that the hippocampal volume is approximately normal with no outliers and x=8.14 cm3 and s=0.7 cm3. Conduct the appropriate test at the α=0.01 level of significance. find the p value
