e) P ( -2.340 < Z <
1.760 )
= P ( Z < 1.760 ) - P ( Z
< -2.340 ) =
0.9608 - 0.0096 =
0.9512 (answer)
4.65)
c) P(Z>z) = 0.1
P(Z≤z) = 1 - 0.1 = 0.9
Z value at 0.9 =
1.282 (excel formula =NORMSINV(
0.9 ) )
value of z =1.282
please revert..
HW 5-Due date: November 13, 2019 For each problem only answer those parts that are listed...
Question 5 Use Appendix Table Ш to determine to 5 decimal places the following probabilities for the standard normal random variable Z: (a) P(Z< 1.29) = (b) P(Z < 2.8) = (c) PlZ > 1.45) = (a) PIZ> 2.15) (e) P(-2.34 < Z < 1.76) =
Ignore my answers and kindly
post full solution to all parts.
Assume Z has a standard normal distribution. Use Appendix Table III to determine the value for z that solves each of the following: (a) P(-2<Z« z) = 0.95. 1.96 (Round the answer to 2 decimal places.) (b) P(-2<Z < z) = 0.99. Z= 2.58 (Round the answer to 3 decimal places.) (c) P(-2 <Z< z) = 0.66. 2= (Round the answer to 3 decimal places.) (d) P(-2<Z<z) = 0.9973....
please answer all parts for the first questions and only the
last part for the second one. I posted the second one already but
the the last part was incorrect. thank you for the help.

PLEASE ANSWER ALL PARTS The mean number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. The males took an average of four English courses with a standard deviation of 0.8. The females took an average of five English courses with a standard deviation of 1.1. Are the means statistically the same? (Use...
I ONLY NEED HELP WITH PART OF PART "B"
I've figured out the test statistic is -1.73 and the degrees of
freedom are 5. However, I'm having a hard time finding the P value
via the chart (which I'm required to learn how to do).I think the
chart immediately bellow this is the one used to find the p-value.
However, I know at least one (or more) of the charts bellow is
what's used. Please let me know which chart...
