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

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:

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

Help i give 5 stars and a crown

REY [17]

Answer:

See below.

Step-by-step explanation:

1a)

Angles:

48, 90, 90, a.

Add:

48 + 90
= 138 + 90
= 228

Subtract:

360 - 228
= 132.

Angle a: 132.

1b)

To get angle h above 180°, We need to add h + 164:

h + 164
= 110 + 164
= 274.

h = 110.

This is how to get h over 180°.
