Answer: H o: u ≤ 10      H α: u > 10

Explanation:

Since the researcher would like to increase the average hourly productivity by more than 10 units. Therefore, the alternative hypothesis which is H α would be greater than 10. Whereas, after going through the test, if the test scores are greater than the significance level then the null hypothesis is rejected which states that it would be less than 10 units. Which the researcher would want to disapprove.

jeka57 [31]

Answer:1.0 and X and Y are substitutes.

Explanation:

Elasticity is the degree of responsiveness of the change in price to a change in quantity demanded. Cross elasticity considers 2 products.

Old price $10

New price $8

Old quantity 20 units

New quantity 25 units

Formula: (change in quantity demandedY/change in priceX) * (old priceX/old quantityY)

{ (25-20) / ($10-$8) } * (10/20) = 1.25

Decision Rule:

> 0 the 2 products are substitutes

< 0 the 2 products are complements

= 0 the 2 products are independent

From the calculation, the products are substitutes because its Elasticity is greater than 0.
