t stat ] A researcher developed a regression model to predict the tear rating of a bag of coffee based on the plate gap in bag-sealing equipment. Data were collected on 30 bags in which the plate gap was varied. An analysis of variance from the regression showed that b1=0.7778 and Sb1=0.2411. a. At the 0.05 level of significance, is there evidence of a linear relationship between the plate gap of the bag-sealing machine and the tear rating of a bag of coffee? b. Construct a 95% confidence interval estimate of the population slope, β1. a. Determine the hypotheses for the test. Choose the correct answer below. A. H0: β1≤0 H1: β1>0 B. H0: β1≥0 H1: β1<0 C. H0: β0≤0 H1: β0>0 Your answer is not correct. D. H0: β0=0 H1: β0≠0 E. H0: β1=0 H1: β1≠0 This is the correct answer. F. H0: β0≥0 H1: β0<0 Compute the test statistic.

t stat ]
A researcher developed a regression model to predict the tear rating of a bag of coffee based on the plate gap in bag-sealing equipment. Data were collected on
30
bags in which the plate gap was varied. An analysis of variance from the regression showed that
b1=0.7778
and
Sb1=0.2411.
a. At the 0.05 level of significance, is there evidence of a linear relationship between the plate gap of the bag-sealing machine and the tear rating of a bag of coffee?
b. Construct a 95% confidence interval estimate of the population slope,
β1.
