3) Let's examine the levels of levels of sodium in the blood. 20 people yield the following results (in mEq/L): ̄y = 136.95 s = 2.544 (a) Test H0: μ = 140 using α = 0.001 (that's not a typo).(b) Figure out the p-value. To do this, take the t value that you calculated in (a) and use R: pt(absolute-value-of-your-t*, df, lower.tail = FALSE)*2 Since it's a two sided test, you need to multiply by 2 at the end. We'll talk more about this in lecture when we do one sided tests; for now just realize that without the “*2” at the end R gives you a one sided p-value. For example, if your t* = 4.65 and you have 67 degrees of freedom you would do: pt(4.65,67,lower.tail = FALSE)*2 and you would get back 1.609352e-05 (c) Is the p-value smaller than α?(d) Why is this (c) important (see also part (a))?

A local tennis pro-shop strings tennis rackets at the tension (pounds per square inch) requested by the customer. Recently a customer made a claim that the pro-shop consistently strings rackets at K lower tensions, on average, than requested. To support this claim, the customer asked the pro shop to string 12 new rackets at 52 psi. Upon receiving the rackets, the customer measured the tension of each and calculated the following summary statistics: x=50 psi, s-3.2 psi. In order to conduct the test, the customer selected a significance level of a 0.05. Interpret this value OA. The probability of concluding that the true mean is less than 52 psi when in fact it is equal to 52 pal is only 0.05. OB. The smallest value of a that you can use and still reject His 0.05 OC. The probability of making a Type 11 error is 0.95. OD. There is a 5% chance that the sample will be biased
