In the event that Yi/n and Y2/n are the individual free relative frequencies of progress related with the two binomial circulations b(n, p1) and b(n, p2), figure n to such an extent that the estimated likelihood that the arbitrary stretch (Yi/n - Y2/n) } 0.05 covers p1 - p2 is at any rate 0.80. Clue: Take pt = 1/2 to give an upper bound to n.

QUESTION 14

Let Y1 < Y2 < Y3 < Y4 < Y5 < 1/6 be the request insights of an arbitrary example of size n = 6 from a circulation of the nonstop sort having (100p)th percentile rrp. Register

(a) P(Y2 < 170.5 < Y5). (b) P(Y1 < 170.25 < Y4). (c) P(Ki < rrag < Y6).

QUESTION 15

For n = long term 2007 model vehicles whose torque is somewhere in the range of 290 and 390, the accompanying estimations give the time in seconds for the vehicle to go from 0 to 60 mph:

6.0 6.3 5.0 6.0 5.7 5.9 6.8 5.5 5.4 4.8 5.4 5.8 (a) Find a 96.14% certainty stretch for the middle, m. (b) The span (yi, y7) could fill in as a certainty stretch for 770.3. Discover it and give its certainty coefficient.

QUESTION 16

An example of n = 9 electrochromic mirrors was utilized to gauge the accompanying low-end reflectivity rates:

7.12 7.22 6.78 6.31 5.99 6.58 7.80 7.40 7.05 (a) Find the endpoints for a surmised 95% certainty span for the middle, m. (b) The span (y3, y7) could fill in as a certainty stretch for m. Discover it and give its certainty
