sweet [91]

Answer:

The calculated value Z = 1.39 <1.96 at 0.05 level of significance

The null hypothesis is accepted

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the mean of the Population = 43

Given that the mean of the sample = 47

Given that the standard deviation of the Population = 25

Given that the sample size 'n' = 76

<u><em>Step(ii):-</em></u>

<u><em>Null hypothesis:H₀: μ = 43</em></u>

<u><em>Alternative Hypothesis: H₁: μ ≠ 43</em></u>

Test statistic

           Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }

          Z = \frac{47-43 }{\frac{25}{\sqrt{76} } }

          Z = 1.39

Level of significance = 0.05

The critical value = 1.96

<u><em>Final answer:-</em></u>

<em>The calculated value Z = 1.39 <1.96 at 0.05 level of significance</em>

<em>The null hypothesis is accepted </em>

vampirchik [111]

Step-by-step explanation:

Todd fills 30 paper cups with ketchup and Yuki fills 27 paper cups with ketchup.

Each paper cup holds 1 ounce

Todd = 30 * 1 = 30 ounces

Yuki = 27 * 1 = 27 ounces

Total ounces = 30 + 27

Later, Todd and Yuki learn that two other company employees completed exactly the same task.

Total ounces = 2 (30 + 27)
