Question

For problem 1 calculate the value of the test statistic, set up the rejection region, determine the p-value, interpret the result and draw the sampling distribution. 1. $H_0: mu = 1000$ $sigma = 200$ $n = 100$ $ar{x} = 980$ $alpha = .01$ $H_A: mu e 1000$

1.
$H_0: mu = 1000$
$sigma = 200$
$n = 100$
$ar{x} = 980$
$alpha = .01$
$H_A: mu 
e 1000$

H0: mu = 1000
sigma = 200
n = 100
arx = 980
alpha = .01
HA: mu
e 1000

Step 1

The hypothesis testing appears to be about a population mean ($\mu$), not a population proportion ($p$). The correct notation should be $H_0: \mu = 1000$ and $H_A: \mu \neq 1000$, with a sample mean ($\bar{x}$) of 980, a population standard deviation Show more…
