You add the ratio numbers to make 10 then divide 150 by 10. (15)
then you multiply 15 by 1:4:5
to make 15:60:75

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
