You are carrying out a χ2 test for independence and have the following information.

The significance level for the test is 10%.
χ2calc=18.7
The expected value for each cell is greater than 5.
Which of the following would lead you to fail to reject the null hypothesis?

#1
χ2crit=16.3

#2
χ2crit=21.2

#3
The calculated p-value is 0.099.

#4
The calculated p-value is 0.011.

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
