At a canning facility, a technician is testing a machine that is supposed to deliver 250 milliliters of product. The technician

Vinvika [58]

Answer:

1.97

Step-by-step explanation:

The null hypothesis is:

$H_{0} = 250$

The alternate hypotesis is:

$H_{1} \neq 250$

Our test statistic is:

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the hypothesis tested(null hypothesis), $\sigma$ is the standard deviation and n is the size of the sample.

In this problem, we have that:

$X = 251.6, \mu = 250, \sigma = 5.4, n = 44$

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$t = \frac{251.6 - 250}{\frac{5.4}{\sqrt{44}}}$

$t = 1.97$
