Part A An adventurous archaeologist crosses between two rock cliffs by slowly going hand over hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope (Figure 1) The rope will break if the tension in it exceeds $3.50 \times 10^4$ N. Our hero's mass is 80.0 kg If the angle $\theta$ is 11.0°, find the tension in the rope. Express your answer in newtons. $T = 2257.43$ Figure <1 of 1 > Part B

Suppose a study reported that the average person watched 4.16 hours of television per day. A random sample of 15 people gave the number of hours of television watched per day shown. At the 5% significance level, do the data provide sufficient evidence to conclude that the amount of television watched per day last year by the average person differed from the value reported in the study? (Note: $\bar{x}$ = 4.533 hours and $s$ = 1.057 hours.) Click here to view a partial table of values of $t_\alpha$ Set up the hypotheses for the one-mean t-test. $H_0$:$\bar{x}$ $oxed{ }$ $oxed{ }$ $H_1$:$\bar{x}$ $oxed{ }$ $oxed{ }$ The test statistic is $t$ = $oxed{ }$ (Round to two decimal places as needed.) Identify the critical value(s). Select the correct choice below and fill in the answer box within your choice. (Round to three decimal places as needed.) A. The critical values are $t_{\alpha/2}$ = $oxed{ }$ B. The critical value is $t_\alpha$ = $oxed{ }$ C. The critical value is $t_\alpha$ = $oxed{ }$ $oxed{ }$ the null hypothesis.
