Answer: 151
Step-by-step explanation:
When the prior estimate of population proportion is available , then the formula for sample size:
, where p= prior estimate of population proportion
z*= critical-value.
E= Margin of error.
Let p be the proportion of of girls "wait for their missionary".
p = 11% =0.11
E= ± 0.03
The critical z-value corresponding to 90% confidence level = z*=1.645 [using z-table ]
Substitute all the values in the above formula , we get
Required sample size :
[Rounded to next integer.]
Thus, the number of observations he needs in his sample = 151
Answer:
The eigen values obtained are not real and thus according to the notation in the question, the eigen values DNE in R

Answer:
0.30 m
Step-by-step explanation:
<u>Explanation</u>:-
Given data is 30 % of m
Algebraic expression:-
The form of the algebraic expression is ax+ by +c
Given data is 30 % of m
here 'of' meaning is multiplied of given term
therefore
The algebraic expression is 0.30 m
Answer:
<h2>The answer is 4</h2>
Step-by-step explanation:
Surface area of a cube = l²
where l is the length of one side
From the question in order to find the surface area first find the length of one side using the volume
Volume of a cube = l³
Volume = 8
So we have
8 = l³
Find the cube root of both sides
l = 2
Now the surface area of the cube = 2²
<h3>= 4</h3>
