A sample of 20 account balances of a credit company showed an average balance of $1,170 and a standard deviation of $125. You wa
Lady_Fox [76]

Answer:

The P-value for this test is P=0.2415.

Step-by-step explanation:

We have to perform an hypothesis testing on the mean of alla account balances.

The claim is that the mean of all account balances is significantly greater than $1,150.

Then, the null and alternative hypothesis are:

H_0: \mu=1150\\\\H_a: \mu>1150

The sample size is n=20, with a sample mean is 110 and standard deviation is 125.

We can calculate the t-statistic as:

t=\dfrac{\bar x-\mu}{s/\sqrt{n}}=\dfrac{1170-1150}{125/\sqrt{20}}=\dfrac{20}{27.95}=0.7156

The degrees of freedom fot this test are:

df=n-1=20-1=19

For this one-tailed test and 19 degrees of freedom, the P-value is:

P-value=P(t>0.7156)=0.2415
