Answer:
The value of the test statistic and the number of degrees of freedom is 2.148 and 11 respectively.
Step-by-step explanation:
The mean annual tuition and fees for a sample of 12 private colleges was $36,800 with a standard deviation of $5000
n = 12
Claim: You wish to test whether the mean tuition and fees for private colleges is different from $33,700
Since n < 30 and sample standard deviation is given so, we will use t test
Formula :
Substitute the values in the formula :
Degree of freedom = n-1 = 12-1 =11
So,. Option D is true
Hence the value of the test statistic and the number of degrees of freedom is 2.148 and 11 respectively.
Answer:
$140.90
Step-by-step explanation:
**22% = 0.22**
X = 109.90 / (1 - 0.22)
X = 109.90 / 0.78
X = 140.90
<span>step 1: 20 -26x 9x = -34x 60
step 2: -17x = -34x 40
step 3: 17x = 40
step 4: x = 40/17
