Answer:
8/3
Step-by-step explanation:
Take the whole number and multiply it by the denominator. 2 * 3 = 6
Then add that to the numerator. 6 + 2 = 8
8 is your new numerator and 3 stays as the denominator.
Hope this helps!
Using the z-distribution, the 90% confidence interval for the difference of proportions is given by: (-0.0534, 0.0434).
<h3>What is the mean and the standard error for the distribution of differences?</h3>
For each sample, the mean and the standard error are given as follows:
.
.
For the distribution of differences, they are given by:
.
<h3>What is the confidence interval?</h3>
The interval is given by:

In this problem, we have a 90% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.645.
Hence the bounds of the interval are:

Answer:
sin 0 = 24/25
cos 0 = 7/25
tan 0 = 24/7
Step-by-step explanation:
hey there!
sine = opposite divided by hypotenuse
the opposite of angle 0 is 24 and the hypotenuse is 25 so sin 0 = 24/25
cosine = adjacent divided by hypotenuse
the adjacent of 0 is 7 and the hypotenuse is 25 so cos 0 = 7/25
Tangent.= opposite divided by adjacent
the opposite of 0 is 24 and the hypotenuse is 7 so tan 0 = 24/7
Answer:
the critical value for 0.87 level of confidence is 1.51
Step-by-step explanation:
Given the data in the question;
level of confidence = 0.87
now,
1 - c = 0.87
c = 1 - 0.87
c = 0.13
c/2 = 0.13/2 = 0.065
now
1 - c/2 = 1 - 0.065 = 0.935
so our level of significance ∝ = 0.935
Now, the critical value will be;
is obtained as follows;
P( Z < z ) = 0.935
so we find the value from ( standard normal distribution table )
P( Z < 1.51 ) = 0.935
Therefore, the critical value for 0.87 level of confidence is 1.51
Answer:
1/4 = 3/12 = 1/12+1/12+1/12
Step-by-step explanation:
Because 1/4 equals 3/12.
