3. Suppose that a new diet barely works and that if everyone in the population of overweight adults were to follow it, the weight losses would be bell-shaped with a mean of 0.1 pound and a standard deviation of 5 pounds. a. Describe the sampling distribution of the sample mean for n = 100. b. Find the standardized statistic corresponding to a sample mean weight loss of 1 pound. c. Using your answer in part (b), comment on whether a sample mean of 1 pound would be unusual in this situation. d. Now suppose that the sample size is increased to n = 900. Repeat parts (a), (b), and (c) in that case. In particular, comment on whether a sample mean of 1 pound would be unusual. e. Compare your answers to parts (c) and (d). Use the comparison to make a general statement about how sample size affects standardized statistics related to the sampling distribution of the sample mean.

The height (feet) of a ball launched in the air t seconds after it is launched is given by: f(t) = - 16t^2 + 299t + 9. Find the height of the ball when it is falling at 110 ft/sec. The height is feet. If necessary, round to two decimal places. If there is more than one correct answer, separate them with commas.

Another student also performed the experiment described in the problem above. Unfortunately, he did not have access to the commercial strain indicator, and instead he had to construct his own Wheatstone Bridge circuit. His strain gage had an initial resistance of 120 Ohm and a gage factor of 2.05. He used the single gage as one leg of the bridge, which he powered with a 6-V battery. The bridge output was fed to an amplifier (gain = 1000), and the amp's output was read by a voltmeter. The student balanced the bridge circuit before he opened the can. After the can was opened, the voltmeter indicated a voltage of -1.57 V. What was the measured pressure for his can? Enter your answer in psi (e.g 120.1) 456 Chapter 12 Strain and Stress: Measurement and Analysis Circumferential strain gage FIGURE 12.22: Instrumented soda can.
