Jack popped some popcorn, but 3 of the 150 kernels did not pop.
den301095 [7]

Answer:

"Snack B and C are same ratio"

Step-by-step explanation:

We need to reduce each fraction and determine whether the ratios are same or not.

3/150 = 1/50

Checking A:

2/75 = 1/37.5

So, this is not equal to 1/50

Checking B:

4/200 = 1/50

THis is the same, so this is equal to 1/50

Checking C:

1/50

it is directly given, so this is equal as well

Hence, Snack B and C are same ratio.

Fudgin [204]

Answer:

See explanation below.

Step-by-step explanation:

Let's take P as the proportion of new candidates between 30 years and 50 years

A) The null and alternative hypotheses:

H0 : p = 0.5

H1: p < 0.5

b) Type I error, is an error whereby the null hypothesis, H0 is rejected although it is true. Here, the type I error will be to conclude that there was age discrimination in the hiring process, whereas it was fair and random.

ie, H0: p = 0.5, then H0 is rejected.
