Chapter 5.4, Problem 50E
Determining the age of an animal can sometimes be a difficult task. One method of estimating the age of harp seals is based on the width of the pulp canal in the canine teeth. To investigate the relationship between age and the width of the pulp canal, researchers recorded age and canal width in seals of known age. The following data on x = Age (in years) and y = Canal length (in millimeters) are a portion of a larger data set that appeared in the paper “Validation of Age Estimation in the Harp Seal Using Dentinal Annuli” (Canadian Journal of Fisheries and Aquatic Science [1983]: 1430–1441):

One operation of a mill is to cut pieces of steel into parts that will later be used as the frame for front seats in an automobile. The steel is cut with a diamond saw and requires the resulting parts to be
within 10.005 inch of the length specified by the automobile company. Data are collected from a sample of 50 steel parts and are shown in the following table. The measurement reported is the
difference in inches between the actual length of the steel part, as measured by a laser measurement device, and the specified length of the steel part. For example, the first value, -0.003,
represents a steel part that is 0.003 inch shorter than the specified length. Complete parts a through c

QUESTION 2
Table Q2 shows Malaysian basketball players height for 2021 FIBA Asia Cup qualification.
a) Calculate the average height of Malaysian basketball players.
An ecologist hypothesizes a relationship between wing span of birds and the width of tree branches they use. The ecologist captured male birds, measured their wing span and other characteristics in
millimeters, and then marked and released them. During the ensuing winter, the ecologist repeatedly observed the marked birds as they foraged for food on tree branches. He noted the branch
diameter on each occasion, and calculated the average branch diameter for each bird in centimeters. The measurement data are below. What can the ecologist conclude with an a of 0.10?
