Answer:
t = 1
Step-by-step explanation:
16 - 2t = t + 9 + 4t
=> 16 - 9 = 7t
=> 7 = 7t
=> t = 1

Answer:
hi i have the same question and im super confused, what was your answer for that question?
Step-by-step explanation:
Answer:
The value of P-value is 0.0472.
Step-by-step explanation:
We are given that you take a simple random sample of 12 apartments in town A and calculate the average price of these apartments. You repeat this for 15 apartments in town B.
Let
= <u><em>true average price of apartments in town A</em></u>
= <u><em>true average price of apartments in town B</em></u>
So, Null Hypothesis,
:
Alternate Hypothesis,
:
The test statistics that have been used here is <u>two-sample t-test statistics</u>, i.e;
The test statistics given to us is 2.1
Now, the P-value of the test statistics is given by the following formula;
P-value = P(
> 2.1)
= P(
> 2.1) = 0.0236
In two-tailed test, P-value is calculated as = 2
0.0236 = <u>0.0472</u>
Hence, the value of the p-value is 0.0472.
Answer:
<h2>In this case,the answer would be option d) given in the answer choices or options or A two-sample t-test for a difference between population means.</h2>
Step-by-step explanation:
- In Statistics,a two sample test is generally used to examine or compare two different population means with the main objective to verify whether the population means are equal or otherwise.
- The two sample t-test basically involves the hypothesis testing to determine or verify the equality between two concerned population means.
- In this case,the two different populations of raccoons are given and the equality of the mean sample weights of the two distinct populations can be determined or evaluated by employing the hypothesis testing method under a two sample t test for measuring difference in two population means.
