A factor in determining the usefulness of an examination as a measure of demonstrated ability is the amount of spread that occur
GarryVolchara [31]

Answer:

Step-by-step explanation:

From the information given :

The null hypothesis H_o : \sigma = 60

The alternative hypothesis  Ha : \sigma \neq 60

Given that:

the sample size n = 21

sample standard deviation s = 68

population standard deviation σ = 60

a) The level of significance \alpha =0.01

b) The chi-square statistics can be calculated as:

\bar X = \dfrac{(n-1)s^2}{\sigma^2}

\bar X = \dfrac{(21-1)68^2}{60^2}

\bar X = \dfrac{(20)4624}{3600}

\bar X = 25.69

The degree of freedom is :

= n - 1

= 21 - 1

= 20
