State whether the standardized test statistic t indicates that you should reject the null hypothesis. Explain. (a) t=2.104 (b) t=0 (c) t=2.005 (d) t=−2.074 -404t t0=2.047 A normal curve is over a horizontal axis labeled z from negative 4 to 4 in increments of 1 and is centered on 0. Vertical line segments extend from the horizontal axis to the curve at t@Sub{0}=2.047, where t@Sub{0}=2.047 is to the right of 0. The area under the curve to the right of t@Sub{0}=2.047 is shaded. (a) For t=2.104, should you reject or fail to reject the null hypothesis? A. Fail to reject H0, because t>2.047. B. Fail to reject H0, because t<2.047. C. Reject H0, because t<2.047. D. Reject H0, because t>2.047.
A liquid-dispensing machine has been designed to fill bottles with 1.0 liter of liquid. The standard deviation of the process is 0.2 liter. A control chart is shown. The chart has horizontal lines drawn at the mean, μ, at μ ±20, and at μ±30. Determine if the process shown is in control or out of control. Explain. Liquid Dispenser Liquid dispensed (inters) 0- Click to select your answer. 4 5 6 7 8 9 10 Observation number G Is the process in control or out of control? Choose the correct answer below. OA. In control, because none of the three warning signals detected a change. OB. Out of control, because a point lies more than three standard deviations from the mean. OC. Out of control, because two out of three consecutive points lie more than two standard deviations from the mean. OD. Out of control, because there are nine consecutive points either above or below the mean.

A hypertension trial is mounted, and 12 participants are randomly assigned to receive either a new medication or a placebo. Each participant takes the assigned medication and their systolic blood pressure, in mm Hg, is recorded after 6 months on the assigned medication. The data are shown in Table 7..9. Is there a difference in mean systolic blood pressure between treatments? Run the appropriate test at α = 0.05. PLEASE SHOW THE ANSWER IN EXCEL FORMAT WITH FORMULAS.
