1	Three adhesives are being tested to see if they are equally effective. Sample data is as follows:
	Adhesive A	Adhesive B	Adhesive C
	75	85	92
	80	88	90
	74	92	90
	80	84	93
	79	81	94
	82	80	96
	91	82	90
	90	86	95
	Assume that the data is normal, that the samples are independent. Perform a hypothesis test at 95% confidence to determine if the population means could be equal. To get full credit, state your null and alternate hypothesis, show the value of your test statistic, show your p-value, and state your conclusion: could all three population means be equal? YES or NO
		Adhesive A	Adhesive B	Adhesive C
	sample mean	81.38	84.75	92.50
	sample std deviation	6.23	3.96	2.39
	n	8	8	8

First, calculate the following:

- The slope- The intercept- Write the equation of the best fit line- Calculate the correlation coefficient.

Using this data, perform a hypothesis tests at 95% confidence to answer this question: Are the slope and correlation coefficient significantly different from zero?

State your null and alternate hypothesis, show your test statistic and show how you made your decision (either p-value or table) and state your conclusion: are the population slope and correlation coefficient different from zero? YES or NO
