A carpenter is making doors that are 2058 millimeters tall. If the doors are too long they must be trimmed, and if they are too

k0ka [10]

Answer:

There is no evidence that the doors are too long and need to be trimmed (H₀ is accepted)

Step-by-step explanation:

$\bar{X} = 2072\\\mu = 2058\\sample size, n = 6\\\alpha = 0.01\\Standard deviation, s = 27$

The null hypothesis, $H_o: \mu = 2058$

Alternative hypothesis, $H_{a}: \mu > 2058$

Test statistic is calculated as follows:

$Z_{test} = \frac{\bar{X} - \mu}{s/\sqrt{n} } \\Z_{test} = \frac{2072 - 2058}{27/\sqrt{6} } \\Z_{test} =1.27$

Find the P-value

P(z > 1.27) = 1 - P(z < 1.27)

P(z > 1.27) = 1 - 0.898

P(z > 1.27) = 0.102

Significance level, α = 0.01

Since P - value(0.102) is greater than α (0.01), the null hypothesis will be accepted.
