When survey data indicated that a coffee company needed to improve its package-sealing process, an experiment was conducted to determine the factors
in the bag-sealing equipment that might be affecting the ease of opening the bags without tearing the inner liner of the bag. Data were collected on 19 bags
and the plate gap on the bag-sealing equipment was used to predict the tear rating of a bag. Complete parts (a) through (c).

a. Construct a 95% confidence interval estimate of the mean tear rating for all bags of coffee when the plate gap is 0.3.
☐ SHYX=0.3☐

A coffee company uses a data-based approach to improving the quality and customer satisfaction of its products. When survey data indicated that the coffee company needed to improve its package-sealing process, an experiment was conducted to determine the factors in the bag-sealing equipment that might be affecting the ease of opening the bag without tearing the inner liner of the bag. One factor that could affect the rating of the ability of the bag to resist tears was the plate gap on the bag-sealing equipment. Data were collected on 19 bags in which the plate gap was varied.
1) Assuming a linear relationship, use the least-squares method to find the regression coefficients b0 and b1.
2) Interpret the meaning of the slope, b1, in this problem. Choose the correct answer below.
A. For each increase of one in the tear rating, the plate gap is expected to increase by b1 units.
B. The approximate tear rating when the plate gap is 0 units is b1.
C. The…

The extent to which theantibodies respond can be measured by looking at a persons titer, which is a measure of the number of antibodies present. The higher the titer is, the more antibodies that are present. The data in Table represent the titers of 11 ill people and 11 healthy people exposed to the tularemia virus in Vermont. Is the level of titer in the ill group greater than the level of titer in the healthy group? Use the α = 0.10 level of significance.arrow_forwardan attempt to develop a model of wine quality as judged by wine experts, data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 12wines, a model was created using the percentages of alcohol to predict wine quality. For those data, SR=18,671 and SST=27,382.Use this information to complete parts (a) through (c) below. Please complete part 3(B) ONLY. Question content area bottom Part 1 a. Determine the coefficient of determination, r2, and interpret its meaning. r2=0.682 (Round to three decimal places as needed.) Part 2 Interpret the meaning of r2. It means that 68.2 of the variation in wine quality can be explained by the variation in alcohol content. (Round to one decimal place as needed.) Part 3 b.
