Step-by-step explanation:
Answer:
a)
We can use the following excel code: "=2*(1-T.DIST(2.48,9,TRUE))"
b)
We can use the following excel code: "=2*(1-T.DIST(3.95,9,TRUE))"
c)
We can use the following excel code: "=2*(1-T.DIST(2.69,9,TRUE))"
d)
We can use the following excel code: "=2*(1-T.DIST(1.88,9,TRUE))"
Step-by-step explanation:
For this case we are testing the following system of hypothesis:
Null hypothesis:
Alternative hypothesis:
The sample size is n=10, so then the degrees of freedom are given by:
In order to calculate the p value we can use the fact that we are conducting a bilateral test so then the p value is given by:
Where represent the calculated or observed statistic.
a) t0= 2.48
We can use the following excel code: "=2*(1-T.DIST(2.48,9,TRUE))"
b) t0= -3.95
We can use the following excel code: "=2*(1-T.DIST(3.95,9,TRUE))"
c) t0=2.69
We can use the following excel code: "=2*(1-T.DIST(2.69,9,TRUE))"
d) t0=1.88
We can use the following excel code: "=2*(1-T.DIST(1.88,9,TRUE))"
