Answer:
The lower bound for a 90% confidence interval is 0.2033
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

90% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The lower bound for a 90% confidence interval is 0.2033
Answer:
The radius is 4.2 and the diameter is always twice the amount of the radius so its 8.4.
Step-by-step explanation:
Answer:
b = h*D +hg^3
Step-by-step explanation:
b/h = D +g^3
Multiply each side by h
h* b/h = h*D +hg^3
b = h*D +hg^3
3x3x3x3 = 81
x.x.x.x = x^4
2x2x2x2 = 16
B. 81x^4/16
B
And sorry kid, I have to take Edge Annuity too and it low-key sucks sometimes but thank god for Brainly
