Less than 75% of workers got their job through internet resume sites. A researcher thinks it has increased.

Vera_Pavlovna [14]

Answer:

H0 : p = 0.75 against H1: p > 0.75 One tailed test.

Step-by-step explanation:

We state our null and alternative hypotheses as

H0 : p = 0.75 against H1: p > 0.75 One tailed test.

In this case H0 is not defined as p≤ 0.75 because the acceptance and rejection regions cannot be set up. Therefore we take the exact value of H0 : p= 0.75.

The claim is that the probability of the workers getting their job through the internet is greater than 75% or 0.75.

As H0 is supposed to be less than we choose H1 to be greater than equality.

Janet is flying a kite on a string that is 75m long. The kite is 62m above the ground. Estimate the distance between Janet and t

Luba_88 [7]

See picture attached.

a² + b² = c²
a² + 62² = 75²
a² = 75² - 62²
a² = 1781
a = √1781
a = 42.2m (nearest tenth)

Ans: T<span>he distance between Janet and the spot on the ground directly beneath the kite is 42.2m</span>
