And based on the claim the system of hypothesis are:

Null hypothesis: $\mu = 26589$

Alternative hypothesis: $\mu \neq 26589$

And the best alternative would be:

b. $H_1: \neq $26,589$

Step-by-step explanation:

For this case we want to test the hypotheis that the true mean is different from 26859. We have the following info given:

$\bar X = 26589$ represent the sample mean

$\sigma =2659$ represent the population deviation

And based on the claim the system of hypothesis are:

Null hypothesis: $\mu = 26589$

Alternative hypothesis: $\mu \neq 26589$

And the best alternative would be:

b. $H_1: \neq $26,589$
