The amounts of 6 restaurant bills and the corresponding amounts of the tips are given in the below.

Bill 97.34 32.98 52.44 49.72 64.30 106.27

Tip 16.00 4.50 7.00 5.28 7.70 16.00

Use a 0.05 confidence level to find the following:

test statistic r = ?

test statistic t = ?

critical value t = ?

the regression equation is y^ =    +      x

If the amount of the bill is $95, the best prediction for the amount of the tip is -----, and a prediction interval estimate of the amount amount of the tip is --- < tip < ---

Confidence Intervals & Hypothesis Tests The manager of a restaurant wants to know if there is a correlation between the amount of a customer’s bill and the percent that they tip. In other words, as people spend more money, do they tend to tip at different rates? With data from a random sample of 157 receipts, he used StatKey to construct a 95% bootstrap confidence interval for r. The results were: [0.018, 0.292]. A. If the manager wanted to conduct...

Researchers examined the relationship between Age (x) in years and blood-brain barrier (BBB) permeability (y) in transfer units. They collected a simple random sample of 24 adults from the New York City region and measured BBB permeability in the hippocampus. They decide to use least-squares regression to estimate the population regression line: μy=α+βx The results from their analysis include: a=0.67,b=0.016,s=0.0181,SEa=0.84,SEb=0.0037,r2=0.84 (a) What does the estimate of the slope for the least-squares regression line tells us? A. For every 1 year...
