Answer:
The p-value will be "0.0549".
Step-by-step explanation:
The given values are:
Time, t = 15 minutes
Df, σ = 25-1 = 24
Now,
⇒
and,
⇒
As we know,
Chi square =
On putting the values in the above formula, we get
⇒ =
⇒ =
⇒ =
Therefore, p-value = 0.0549
The p-value determined > 0.05, the null hypothesis also isn't dismissed at point 0.05.
Five thousand two hundred eight six divided by twenty one is two hundred fifty one and seven hundred fourteen thousandths two hundred eighty six millionths :)
Answer:
A) The proportions of wins is the same for teams wearing suits as for teams wearing jeans
Step-by-step explanation:
Although the question says that they will "test the claim at the 0.05 level that the proportion of win is the same for teams wearing sutis as for the teams wearing the jeans", the claim, that will be expressed in the alternative hypothesis, is that there is a significant difference between the two proportions.
The null hypothesis, the one that this test try to nullify, will state that there is no significant difference between the two proportions. Or, saying the same, that the proportions are equal.
The right answer is A, which states that the two proportions (as this is a test on the difference of proportions) are equal.
