Answer:
Follows are the solution to the given points:
Step-by-step explanation:
In point A:

In point B:

In point C:
For df = 70, the top 5% critical t score
tcrit = 1.666914479
Thus,

In point D:
For df = 70, the top 5% critical t score
tcrit = -1.666914479

In point E:
The lower cutoff is 0.10 in the center, which would be around 80 %. The critical point therefore is
tcrit = -1.293762898

In point F:
The lower cutoff is 0.90 in the center, which would be around 80 %. The critical point therefore is
tcrit = 1.293762898

Answer:
Approximately 12 days.
Step-by-step explanation:
No. of days = 2214.5/(9x21.14)
= 2214.5/190.26
