Anton [14]

Answer:

We do not reject the Null Hypothesis

Step-by-step explanation:

From the question we are told that:

Sample size n=23

Population mean \mu=9.02cm^3

Sample mean \=x=8.16

Standard deviation \sigma=0.7cm^3

Significance level \alpha =0.01

Generally the Null and and alternative Hypothesis are as follows

 H_0:\mu=9.02cm^3

 H_a:\mu

Therefore t critical Value is

 t\ critical\ Value=(\alpha,df)

 t\ critical\ Value=(0.01,22)

Where

  df=n-1\\\\df=23-1=>22

Therefore

From t Table

 t value=-2.8

Generally the equation for Z Critical is mathematically given by

 t=\frac{\=x-\mu}{\frac{\sigma}{\sqrt{n} } }

 t=\frac{8.16-9.02}{\frac{0.7}{\sqrt{23} } }

 t=-5.89

Therefore

Since the t test statistics is greater than the Critical value

Hence,we do not reject the Null Hypothesis
