Answer:
The alternative hypothesis is:
<em>Hₐ</em>: The workers with automatic dispensers are more productive than restaurant with manual dispensers.
Step-by-step explanation:
In this case we need to determine whether the workers with automatic dispensers are significantly more productive than restaurant with manual dispensers.
To test this a random sample of 9 workers from a restaurant with automatic dispensers and 9 works from a restaurant with manual dispensers are selected.
The significance level of the test is, <em>α</em> = 0.01.
A Mann-Whitney U test is used to determine whether the randomly selected value from one population is either more than or less than the same value selected from another population.
The hypothesis can be defined as follows:
<em>H₀</em>: The workers with automatic dispensers are as productive as restaurant with manual dispensers.
<em>Hₐ</em>: The workers with automatic dispensers are more productive than restaurant with manual dispensers.

Answer:
c. x = -1/15
Step-by-step explanation:
5/2x - 1/3 = -1/2 [multiply the whole equation by 6 (lowest common denom)
15x - 2 = -3 [add 2 on both sides of equation
15x = -1 [divide both sides by 15 to isolate x]
x = -1/15
