Answer:
[tex] P(t_{16} > 2.120)[/tex]
And we can calculate this with the complement rule, and with the following Excel code:
"=1-T.DIST(2.12,16,TRUE)"
And we got: [tex] P(t_{16} > 2.120)=0.024995 [/tex]
[tex] P(t_{16} < 1.337)[/tex]
And we can calculate this with the following Excel code:
"=T.DIST(1.337,16,TRUE)"
And we got:
[tex] P(t_{16} < 1.337)=0.900039 [/tex]
Step-by-step explanation:
For this case we know that we have a t distribution with df = 16
[tex] t (16)[/tex]
And we want this probability:
[tex] P(t_{16} > 2.120)[/tex]
And we can calculate this with the complement rule, and with the following Excel code:
"=1-T.DIST(2.12,16,TRUE)"
And we got: [tex] P(t_{16} > 2.120)=0.024995 [/tex]
For the other case we have this:
[tex] P(t_{16} < 1.337)[/tex]
And we can calculate this with the following Excel code:
"=T.DIST(1.337,16,TRUE)"
And we got:
[tex] P(t_{16} < 1.337)=0.900039 [/tex]
