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.
1/2 because there are 3 odd numbers on a number cube and 6 numbers in total and 3/6 simplified is 1/2
Answer:
d^2 = <y2-y1>^2 + <x2 -x1) ^2
so

Answer:
x
32
Step-by-step explanation:
"A number at least 32"
Let's use x as the number
x32
Reason: at least means greater than or equal to
