Volume of the sphere is 300 m³

Step-by-step explanation:

  • Step 1: Calculate volume of the sphere using the formula V = 4/3πr³, where r = d/2 = 4m

⇒ V = 4/3 × 3.14 × 4³ = 267.95 = 300 m³ (rounding off to the nearest hundredth)

drek231 [11]

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 .
