Q9. Consider the baseball coefficient of restitution data as follows: 0.6248, 0.6520, 0.6226, 0.623O, 0.6237, 0.6368, 0.6280, 0.6131, 0.6118, 0.6220, 0.6096, 0.6223, 0.6159, 0.6151, 0.6300, 0.6297, 0.6298, 0.6121, 0.6107, 0.6435, 0.6192, 0.6548, 0.6392, 0.5978, 0.6351, O.6128, 0.6134, 0.6275, 0.6403, 0.6310, 0.6261, 0.6521, 0.6065, 0.6262, 0.6049, 0.6214, 0.6262, 0.6170, 0.6141, 0.6314. Suppose that any baseball that has a coefficient of restitution that equal or exceeds 0.63 is considered too lively. Find a 95% Cl of proportion of too lively. 0.116 sus 0.384 0.039

(3-B is needed to answer it I am only asking for question 4.) 3) You go out and collect the following estimates of earthworms / acre:54,276 57,378 51,108 66,190 66,232 59,018 57,159These data yield the following: ̄y = 59,765.86, and s = 5,689.606a) Construct a 90% CI for these data.b) Construct a 99% CI for these data.c) Darwin once estimated that an acre of soil had about 50,000 worms in it. Is his estimateconsistent with the data above? (Historical note: His estimate was considered way too high inhis day). 4) Consider the results of 3(b). Notice that all the data fit within the 99% confidence interval. Is thisusually the case (in other words, will a 99% CI contain most of the observations)?Caution: a lot of people get this wrong! Here's a hint: suppose you had measured the worms in6000 acres (instead of just 7). What happens to the confidence interval? If you're not sure,substitute 6,000 for 7 in your calculation for (b) to see what happens.

a) Given the Following Data & (DC) = 95% , Find the (CI)!22 9 6 12 18 14 7 104 21 18 31 14 25 15 23

We asked UST employees to tell us how many megabytes of memory (RAM) they have on their computer.  We would like to test to see if the mean amount of memory is the same for three different academic departments.  We have the memory amounts for six faculty members' machines in the three departments shown below.                                         Dept. 1       Dept. 2    Dept. 3                               1           2048          4096       4096                               2           1024          2048       4096                               3           1024          2048       8192      computer   4           2048          4096       8192                               5           1024          2048       4096                               6            2048          8192       2048    Here is the ANOVA table: Source DF Adj SS Adj MS F-Value P-Value Factor x 39263346 19631673 x.xx 0.025 Error xx 61691221 4112748     Total xx…
