The number of tests that it would take for the probability of committing at least one type I error to be at least 0.7 is 118 .
In the question ,
it is given that ,
the probability of committing at least , type I error is = 0.7
we have to find the number of tests ,
let the number of test be n ,
the above mentioned situation can be written as
1 - P(no type I error is committed) ≥ P(at least type I error is committed)
which is written as ,
1 - (1 - 0.01)ⁿ ≥ 0.7
-(0.99)ⁿ ≥ 0.7 - 1
(0.99)ⁿ ≤ 0.3
On further simplification ,
we get ,
n ≈ 118 .
Therefore , the number of tests are 118 .

Answer:
The temperature of coffee becomes 163.08 Fahrenheit.
Step-by-step explanation:
The Newton's law of cooling can be mathematically written as
Applying the limits in the above relation as
At t = 0 ; T= 200 F
At t =10 ; T = 180 F
Applying the limits in the above relation as
At t = 10 ; T= 180 F
At t =20 ; T = T F
