2. A coin is dropped from a height of 1.0000 m for 10 times. The amount of timerequired to reach the floor is measured for each drop.(a) Show a tabular presentation of data for the 10 trials by providing"estimated" time for each case. [If you have trouble giving "estimated" time,perform the experiment.](b) Based on your provided data, calculate the error propagated in theexperiment. Calculate i ±o.

Given information: Height from which coin is dropped=1 mNumber of times coin is dropped=10

A regression of average monthly expenditure (AME, measured in euros) on average monthly income (AMI, measured in euros) using a random sample of college-educated full-time workers earnings €100 to €1.5 million yields the following: AME = 710.7 + 8.8 × AMI, R2 = 0.030, SER = 540.30 d. What does the regression predict will be the expenditure of a person with an income of €100? With an income of €200? e. Will the regression give reliable predictions for a person with an income of €2 million? Why or why not? ( f. Given what you know about the distribution of earnings, do you think it is plausible that the distribution of errors in the regression is normal?

Stoaches are fictional creatures, sometimes mistaken for mome raths. Suppose a two-tailed t-test is conducted to test for a difference between the population means of adult female stoach weights and adult male stoach weights. The female sample has 13 weights, and the male sample has 7 weights. The t-statistic for the test is -0.20542. What is the p-value? (Give your answer to 4 decimal places.) p-value:
For an alpha = .025 and degrees of freedom, df = 15, what is the one-tailed t-value? Give your answer exactly as it appears in the table, with three decimal places.
(a) In one or two sentences, describe how your experiment went; for example, mention any difficulties that you faced along the way. Then present a table of your collected data, similar in layout to Table 3 of Unit 10 (Subsection 3.4). Indicate clearly the units in which you made your measurements (for example, millimetres) and the measurements that correspond to seedlings whose stems were cut during their growth. Then proceed to part (b) of the question. If, however, you were unable to collect data of your own, then state this and explain why. Instead of presenting results in a table, draw stemplots for each of the two samples of data given in Table 1, including only measurements from seedlings whose stems were cut during growth. Also, give the main reason for producing such stemplots in the context of a t-test, and comment on the shape of the stemplots relative to this reason.
