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 84 preserved Etruscan male skulls was 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. Brothwell, “The Evaluation of Metrical Data in the Comparison of Ancient and Modern Bones.” In Medical Biology and Etruscan Origins, G. Wolstenholme and C. O’Connor, eds., Little, Brown&Co., 1959]

The height of 10 skeletons (denoted by the variable stature) and the length of the middle metacarpal
bone were measured (the metacarpal bones are in the hand between the wrist and fingers). The
skeletal height is measured in centimeters and the metacarpal length in millimeters. The scatterplot
is given below.

answer.
3. Estimate the correlation between metacarpal length and stature. No calculations are necessary.
4. If the height and metacarpal length of the skeletons had been measured in inches, instead of
centimeters and millimeters, how would the correlation between stature and metacarpal length
for these 10 skeletons have been affected? Explain.

Find the value of SSE if P = 4, n = 12, and MSE= 5.arrow_forwardA company that manufactures golf balls produces a new type of ball that is supposed to travel significantly farther than the company’s previous golf ball. To determine this, 40 new-style golf balls and 40 original-style golf balls are randomly selected from the company’s production line on a specific day. The balls are then placed in a bag and shaken. A golf pro then selects a ball and hits it using a driver. The distance the ball travels is then measured. The bag is shaken again, and the golf pro selects another ball and hits it with the same driver. He continues this procedure until all 80 of the golf balls are hit. Which of the following is a benefit of having replication in the experiment? A)Repeating the experiment will allow the company to compare the distances traveled by the new type of golf ball from both experiments. B)Having a large number of each type of golf ball will allow for a good comparison of the differences in distances traveled for the two types of balls.…arrow_forwardA crayon manufacturer is comparing the effects of two kinds of yellow dye on the brittleness of crayons.

The results are as follows: Dye A: 1.0 2.0 1.2 3.0 Dye B: 3.0 3.2 2.6 3.4 a) Can you conclude that the mean strength of crayons made with dye B is greater than that of crayons made with dye A? b) Can you conclude that the mean strength of crayons made with dye B exceeds that of crayons made with dye A by more than 1 J?arrow_forward

She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 287 trials, the touch therapists were correct 130 times. Complete parts (a) through (d).

Half of the students were given a stack of money to count and the other half got a stack of blank pieces of paper. After the counting task, the participants were asked to dip their hands into bowls of very hot water (122° F) and rate how uncomfortable it was. The following data show ratings of pain similar to the results obtained in the study.
