Answer:

Null hypothesis: The time it will take the pizza shop to make and deliver the pizza is 30 minutes.

Alternate hypothesis: The time it will take the pizza shop to make and deliver the pizza is greater than 30 minutes.

Explanation:

A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing.

It is always expressed using the equality sign.

An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected.

It is always expressed using any of the inequality signs.

monitta

Answer:

$9.05

Explanation:

the information about prices and costs is missing, so I looked it up:

contribution margin per yard for silk = $18 - $4.10 - $2.70 - $3.51 - $0.90 = $6.79

contribution margin per yard for polyester = $10.20 - $0.80 - $2.90 - $3.77 - $0.60 = $2.13

contribution margin per machine hour:

silk = $6.79 x 1/0.75 = $9.05

polyester = $2.13 x 1/0.5 = $4.16
