6) 0.5
Step-by-step explanation:
We are given the following in the question:
Sample space, S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}.
1. The probability of getting exactly one tail
P(Exactly one tail)
Favorable outcomes ={HHT, HTH, THH}
2. The probability of getting exactly two tails
P(Exactly two tail)
Favorable outcomes ={ HTT,THT, TTH}
3. The probability of getting a head on the first toss
P(head on the first toss)
Favorable outcomes ={HHH, HHT, HTH, HTT}
4. The probability of getting a tail on the last toss
P(tail on the last toss)
Favorable outcomes ={HHT,HTT,THT,TTT}
5. The probability of getting at least one head
P(at least one head)
Favorable outcomes ={HHH, HHT, HTH, HTT, THH, THT, TTH}
6. The probability of getting at least two heads
P(Exactly one tail)
Favorable outcomes ={HHH, HHT, HTH,THH}
Answer:
The range of the <em>p</em>-value is: 0.050 < <em>p</em>-value < 0.100.
Step-by-step explanation:
For checking the equivalence of two population variances of independent samples, we use the <em>f</em>-test.
The test statistic is given by:
It is provided that the hypothesis test is one-tailed.
The computed value of the test statistic is:
<em>F</em> = 4.23.
The degrees of freedom of the numerator and denominator are:
Use MS-Excel to compute the <em>p</em>-value as follows:
Step 1: Select function fX → F.DIST.RT.
Step 2: A dialog box will open. Enter the values of f-statistic and the two degrees of freedom.
*See the attachment below.
Step 3: Press OK.
The <em>p</em>-value is, 0.0728.
The range of the <em>p</em>-value is:
0.050 < <em>p</em>-value < 0.100
