A photoconductor film is manufactured at a nominal thickness of 25 mils. The product engineer wishes to increase the mean speed of the film, and believes that this can be achieved by reducing the thickness of the film to 20 mils. Eight samples of each film thickness are manufactured in a pilot production process, and the film speed (in microjoules per square inch) is measured. For the 25-mil film, the sample data result is = 1.15 and 81 = 0.11, while for the 20-mil film, the data yield 2 = 1.06 and 82 = 0.09. Note that an increase in film speed vould lower the value of the observation in microjoules per square inch. (a) Do the data support the claim that reducing the film thickness increases the mean speed of the film? Use a = 0.10 and assume that the two population variances are equal and the underlying population of film speed is normally distributed. What is the P-value for this test? Round your answer to three decimal places (e.g. 98.765). The data the claim that reducing the film…

One operation of a mill is to cut pieces of steel into parts that are used in the frame for front seats in an automobile. The steel is cut with a diamond saw, and the resulting parts must be cut to be within 0.005 inch of the length specified by the automobile company. The measurement reported from a sample of 100 steel parts (stored in “Assignment 2 – Steel.xlsx” ) 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 observation, -0.002, represents a steel part that is 0.002 inch shorter than the specified length. -0.0042 0.0057 0.0031 -0.0085 -0.0087 0.0083 0.0035 -0.0070 0.0040 0.0080 0.0094 -0.0036 -0.0067 0.0052 0.0100 -0.0010 0.0077 0.0010 -0.0060 -0.0025 -0.0022 -0.0097 0.0047 0.0060 0.0006 -0.0044 0.0015 0.0089 -0.0039 -0.0064 -0.0046 -0.0096 0.0021 -0.0071 -0.0020 0.0009 -0.0028 -0.0060 0.0001 -0.0057 -0.0062 0.0054 0.0061 0.0090 0.0004 0.0051…
The mortality rate from melanoma (skin cancer) during the 1950s was recorded for each of the 48 contiguous United States, plus Washington, D.C. (as reported by Fisher and Van Belle (1993) and found at http://www.stat.psu.edu/~lsimon/stat501wc/sp05/data/ The following is the scatterplot of the data: Mortality per 10 million 225 200 175 150 125 100- 30 35 Scatter plot 40 Latitude r=-.83 45 50 The plot shows a negative linear relationship between the latitude of the state and melanoma mortality rate. Which of the following is an appropriate interpretation of the negative relationship shown in the scatterplot above? A. O The more southern the state, the more people that died of melanoma. B. O The more southern the state, the higher the melanoma death rate. C. The more northern the state, the higher the melanoma death rate.
