Answer:
The sample statistics follows a standard normal distribution since the sample size are large enough.
Step-by-step explanation:
Given that:
<u>First population:</u>
Sample size = 49
Population standard deviation = 3
Sample mean = 10
<u>Second population:</u>
Sample size = 64
Population standard deviation = 4
Sample mean = 12
The sample statistics follows a standard normal distribution since the sample size are large enough.
The null and alternative hypotheses can be computed as:
Level of significance = 0.01
Using the Z-test statistics;
Z = - 3.037
Z - 3.04
The P-value = 2P (z < -3.04)
From the z tables
= 2 × (0.00118)
= 0.00236
Thus, since P-value is less than the level of significance, we fail to reject the null hypotheses
Answer:
The corresponding point is <em>(-8, -6).</em>
Step-by-step explanation:
Given that
(-6,-6) lies on the graph of
A function is represented in the form:
i.e. (-6,-6) means value of x = -6 is put and value y came out as -6.
Now, we have to find the corresponding point on .
We know the value of
Let us find the value of x where becomes equal to -6
So, let us put value of in
:
(as per given statement)
So, the corresponding point is <em>(-8, -6).</em>
