Business Statistics

A researcher is testing the null hypothesis that there is no relationship between two continuous variables (customers’ loyalty: continuous dependent variable and service quality: continuous independent variable). From a sample of n = 25, she determines that b1 = +4.8 and Sbl = 1.6.

a) What is the value of tSTAT?

b) What statistical decision should the researcher make? (for 95% confidence intervals, the t value is -2.145 and +2.145).

c) Construct a 95% confidence interval estimate of the population slope, f3i (for 95% confidence intervals, the t value is -2.145 and +2.145).
