Answer:

The value of the test statistic is 59.75.

Step-by-step explanation:

The test statistic for the population standard deviation is:

$\chi^2 = \frac{n-1}{\sigma_0^2}s^2$

In which n is the sample size, $\sigma_0$ is the value tested and s is the sample standard deviation.

A sample of 45 bottles of soft drink showed a variance of 1.1 in their contents.

This means that $n = 45, s^2 = 1.1$

The process engineer wants to determine whether or not the standard deviation of the population is significantly different from 0.9 ounces.

0.9 is the value tested, so $\sigma_0 = 0.9, \sigma_0^2 = 0.81$

What is the value of the test statistic

$\chi^2 = \frac{n-1}{\sigma_0^2}s^2$

$\chi^2 = \frac{44}{0.81}1.1 = 59.75$

The value of the test statistic is 59.75.

an aeroplane is flying with a help of 300 km per hour who much distance will it cover in 160 minute

uysha [10]

Answer:

800 km

Step-by-step explanation:

Does the plane have a speed of it's own? I don't see it, so will assume the plane is simply travelling at 300 km/h.

(300 km/hr)*(1 hr/60 min) = 5 km/min

(5 km/min)*(160 min) = 800 km in 160 minutes
