Suppose a company makes skateboard wheels with a diameter of 64 mm. When the machine that manufactures the wheels is functioning
andreyandreev [35.5K]

Answer:

z=\frac{65-64}{\frac{3.5}{\sqrt{49}}}=2    

Now we can find the p value based in the alternative hypothesis and we got:

p_v =2*P(z>2)=0.0455  

Step-by-step explanation:

Information given

\bar X=65 represent the sample mean

\sigma=3.5 represent the population standard deviation

n=49 sample size  

\mu_o =64 represent the value to verify

z would represent the statistic  

p_v represent the p value

System of hypothesis

We want to verify if the true mean for this case is 64 or no, the system of hypothesis would be:  

Null hypothesis:\mu = 64  

Alternative hypothesis:\mu \neq 64  

The statistic is given by:

z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}  (1)  

The statistic for this case is given by:

z=\frac{65-64}{\frac{3.5}{\sqrt{49}}}=2    

Now we can find the p value based in the alternative hypothesis and we got:

p_v =2*P(z>2)=0.0455
