Nan compos-mentis, a technical consultant, claims that she can increase average hourly productivity for the fabricators at stryker manufacturing by more than 10 units per worker. to support her claim, nan plans to select a sample of workers, provide the workers in the sample with special training, and then use results from the sample in a hypothesis test designed to establish whether the training has had the desired effect. what null and alternative hypotheses would you recommend here?

Step-by-step explanation:

given that Nan Compos-Mentis, a technical consultant, claims that she can increase average hourly productivity for the fabricators at Stryker Manufacturing by more than 10 units per worker.

To support her claim, Nan plans to select a sample of workers, provide the workers in the sample with special training, and then use results from the sample in a hypothesis test designed to establish whether the training has had the desired effect.

Here her matter of interest is whether training improves the mean score of hourly productivity

Hence the hypotheses should be

A right tailed test.

it is a function because for every x value there is only one y value

for every x value there is only one y value

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
