Acrylic bone cement is commonly used in total joint replacement to secure the artificial joint. Data on the force (measuredin Newtons, N) required to break a cement bond was determined under two different temperature conditions and in twodifferent mediums appear in the following table.Temperature MediumData on Breaking Force22 degreesDry100.5, 142.6, 194.8, 118.4, 176.1, 213.137 degrees22 degreesDryWet303.3, 339.1, 288.8, 306.8, 305.2, 327.5385.4, 367.2, 322.6, 307.4, 357.9, 321.437 degreesWet363.6, 376.8, 327.7, 331.9, 338.1, 394.6(a) Estimate the difference between the mean breaking force in a dry medium at 37 degrees and the meanbreaking force at the same temperature in a wet medium using a 90% confidence interval.

A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are heights (in centimeters) of randomly selected presidents along with the heights of their main opponents. Complete parts (a) and (b) below. Height (cm) of President 185 170 179 191 194 179 9 Height (cm) of Main Opponent 170 184 174 166 194 182 Identify the test statistic. t= 0.57 (Round to two decimal places as needed.) Identify the P-value P-value = 0.286 (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-value is greater than the significance level, fail to reject the null hypothesis. There is not sufficient evidence to support the claim that presidents tend to be taller than their opponents. b. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature of the confidence interval leads to the same conclusion reached in part (a)? The confidence interval…
The first Batman movie was made over 50 years ago in 1966. Över the years, Batman has been played on screen by a number of actors and even by a Lego figure in the Lego Batman movies. In the original comic books, Batman was 188 centimeters tall (about 6'2") and weighed 95 kilograms (about 210 pounds). The article "50 Years of Batman on Film: How Has His Physique Changed?"t included the heights and weights of all of the onscreen Batmen in the table below. Batman Height (cm) Weight (kg) Comic book 188 95 Lego Batman 4 0.005 Adam West 188 91 Michael Keaton 178 72 Val Kilmer 183 93 George Clooney 180 78 Christian Bale 183 82 Ben Affleck 193 98 A USE SALT With x = height and y = weight, the equation of the least squares regression line is ŷ = -3.0112 + 0.4881x. %D (a) Calculate the residuals.
