Answer:
6, - 36 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = -
f(x) = x² + 12x ← is in standard form
with a = 1, b = 12, c = 0 , then
x = - = - 6
Substitute x = 6 into f(x) for corresponding value of y
f(6) = 6² + 12(- 6) = 36 - 72 = - 36
vertex = (6, - 36 )
Answer:
The test statistics is
The critical value is
The null hypothesis is rejected
Step-by-step explanation:
From the question we are told that
The sample size for men is
The sample proportion of men that own a cat is
The sample size for women is
The sample proportion of women that own a cat is
The level of significance is
The null hypothesis is
The alternative hypothesis is
Generally the test statistic is mathematically represented as
=>
=>
The critical value of from the normal distribution table is
The p-value is obtained from the z-table ,the value is
=>
Given that the then we reject the null hypothesis
