Answer:
z= 3.63
z for significance level = 0.05 is ± 1.645
Step-by-step explanation:
Here p = 42% = 0.42
n= 500
We formulate our null and alternative hypotheses as
H0: p= 0.42 against Ha : p> 0.42 One tailed test
From this we can find q which is equal to 1-p= 1-0.42 = 0.58
Taking p`= 0.5
Now using the z test
z= p`- p/ √p(1-p)/n
Putting the values
z= 0.5- 0.42/ √0.42*0.58/500
z= 0.5- 0.42/ 0.0220
z= 3.63
For one tailed test the value of z for significance level = 0.05 is ± 1.645
Since the calculated value does not fall in the critical region we reject our null hypothesis and accept the alternative hypothesis that more than 42% people owned cats.
Answer:
answer is 9
Step-by-step explanation:
p - ( q - (m +q) )
make m = 4
p = 5
q = 3
5 - ( 3 - ( 4+3) )
5 - ( 3 - 7 )
5 - - 4
= 9
Alfonso will need to work 8 hours. What i did was multiply 8 by 6 which is 48 then subtracted 48 by 144 and got 96 then you divide that by 12 which is 8, and that is how many hours he will have to work.
Answer:
A. 4.5
Step-by-step explanation:
According to my graphing calculator, e^1.5=4.5 which is rounded to the nearest tenth.
Answer: e^1.5 = 4.482
Step-by-step explanation:
Given:
We need to find the value of function at x=1.5
Put x=1.5 into f(x)
Now we will verify the result using graph.
First we draw the graph of f(x) and a vertical line x=1.5
Please see the attachment for graph.
Hence, The value of
