Answer:
y=107
x=73
z=73
Step-by-step explanation:
y and 107 are vertical angles, which means that they're the same value because they're vertically across from each other.
107 and x are supplementary angles, so x=180-107 or 73.
x and z are also vertical angles, so x=z=73.
Answer:
So the answer for this case would be n=94 rounded up to the nearest integer
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
Solution to the problem
The margin of error is given by this formula:
(a)
And on this case we have that ME =120 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The confidence2 level is 98% or 0.98 then the significance level would be
and
, the critical value for this case would be
, replacing into formula (b) we got:
So the answer for this case would be n=94 rounded up to the nearest integer
