When his blood sugar reaches 170 mg/dL, he goesout for a run at a pace of 10 minutes per mile. On different days, he runsdifferent distances and measures his blood sugar after completing his run.Note: The preferred blood sugar level is in the range of 80 to 120 mg/dL. Levelsthat are too low or too high are extremely dangerous. The data generated aregiven in the following table.Distance 22|2.52.5333.53.5 444.5 4.5(miles)Blood136 146 131 125 120 116 104 9585 94 83| 75sugar(mg/dl)a) Construct a scatter diagram for these data. Does the scatter diagram exhibit alinear relationship between distance run and blood sugar level?b) Find the predictive regression equation of blood sugar level on the distance run.c) Give a brief interpretation of the values of ßo and ß, calculated in part b.d) Plot the predictive regression line on the scatter diagram of part a and show theerrors by drawing vertical lines between scatter points and the predictiveregression line.e) Calculate the predicted blood sugar level count after a run of 3.1 miles (5kilometers).f) Estimate the blood sugar level after a 10-mile run. Comment on this finding.2. Hanna Properties specializes in custom home resales in the EquestrianEstates, an exclusive subdivision in Phoenix, Arizona.

A new process for producing synthetic diamonds can be operated at a profitable level only if the average weight of the diamonds is greater than 0.5 karat. To evaluate the profitability of the process, six diamonds are generated, with recorded weights 0.46, 0.61, 0.52, 0.48, 0.57 and o.54 karat. Do the six measurements present sufficient evidence to indicate that the average weight of the diamonds produced by the process is in excess of 0.5 karat? Use 5% level of significance
A taxi company manager is trying to decide whether the use of radial tires instead of regular belted tires improves fuel economy. Twelve cars were equipped with radial tires and driven over a prescribed test course. Without changing drivers, the same cars were then equipped with regular belted tires and driven once again over the test course. The gasoline consumption, in kilometers per liter, was recorded as follows: (image attached) Can we conclude that cars equipped with radial tires give better fuel economy than those equipped with belted tires? Assume the populations to be normally distributed. Use both p-value and critical value approach.
The Etruscans. Anthropologists are still trying to unravel the mystery of the origins of the Etruscan empire, a highly advanced Italic civilization formed around the eighth century B.C. in central Italy. Were they native to the Italian peninsula or, as many aspects of their civilization suggest, did they migrate from the East by land or sea? The maximum head breadth, in millimeters, of 70 modern Italian male skulls and that of 84 preserved Etruscan male skulls were analyzed to help researchers decide whether the Etruscans were native to Italy. The resulting data can be found on the WeissStats site. [SOURCE: N. Barnicot and D.

A researcher hypothesizes that electrical stimulation of the lateral habenula will resultin a decrease in food intake (in this case, chocolate chips) in rats. Rats undergostereotaxic surgery and an electrode is implanted in the right lateral habenula.

To test compliance with authority, a classical experiment in social psychology requires subjects to administer increasingly painful electric shocks to seemingly helpless victims who agonize in an adjacent room.* Each subject earns a score between 0 and 30, depending on the point at which the subject refuses to comply with authority—an investigator, dressed in a white lab coat, who orders the administration of increasingly intense shocks. A score of 0 signifies the subject's unwillingness to comply at the very outset, and a score of 30 signifies the subject's willingness to comply completely with the experimenter's orders. Ignore the very real ethical issues raised by this type of experiment, and assume that you want to study the effect of a “committee atmosphere” on compliance with authority. In one condition, shocks are administered only after an affirmative decision by the committee, consisting of one real subject and two associates of the investigator, who act as subjects but, in…
