The mean yield of corn in the United States is about 135 bushels per acre. A survey of 40 farmers this year gives a sample mean

Ostrovityanka [42]

Answer:

$z = \frac{138.8-135}{\frac{10}{\sqrt{40}}}= 2.403$

Step-by-step explanation:

Data given and notation

$\bar X=138.8$ represent the sample mean

$\sigma = 10$ represent the population standard deviation

$n=40$ sample size

$\mu_o =135$ represent the value that we want to test

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

Solution to the problem

We need to conduct a hypothesis in order to check if the true mean for the bushlels per acre is not 135, the system of hypothesis would be:

Null hypothesis: $\mu = 135$

Alternative hypothesis: $\mu \neq 135$

And the z statistic is given by:

$z= \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z = \frac{138.8-135}{\frac{10}{\sqrt{40}}}= 2.403$
