# Question

Refer to Exercise 10 where we are trying to link the number of customer choices (x) and the level of customer confidence (y). The estimated regression equation turned out to be ˆy =66 6.8x. Is the sample slope (b = – 6.8) significantly different from 0 at the 5% significance level? Explain the implications of your answer.
