Answer:
0.016
Step-by-step explanation:
To find the probability we have to Divide the number of events by the total number of possible outcomes. This will result in the probability of the single event.
Therefore, the formula of probability is
In the given case,
Which is our required answer.
Answer:
Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Step-by-step explanation:
1)Formulate the hypothesis that first variance is equal or greater than the second variance
H0: σ₁²≥σ₂² against the claim that the first instructor's variance is smaller
Ha: σ₁²< σ₂²
2) Test Statistic F= s₂²/s₁²
F= 84.8/ 58.9= 1.4397
3)Degrees of Freedom = n1-1= 10-1= 9 and n2 = 10-1= 9
4)Critical value at 10 % significance level= F(9,9)= 2.4403
5)Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
I believe the correct answer is -2

Answer:
On Thursday, she was walking at a good pace but then started to run because of the rain and she ran back home because she had to get to dinner so her parents do not get mad.
