Answer:
Step-by-step explanation:
Given that
sample size n = 55: x bar = 654.16 and s = sample sd = 162.34
Std error = 162.34/sqrt 55 = 21.889
For 95% CI we can use t critical value as population std dev is not known.
df = 54
t critical = 2.004
Margin of error = 2.004 *21.889 = 43.866
Confidence interval lower bound = 654.16-43.866 =610.294
Upper bound = 654.16+43.866=698.026
Confidence interval rounded off at 95% = (610.29, 698.23)
Answer:
I think it might be -2....
Answer:
2. is 6290
3. is 13540
Step-by-step explanation:
Formula for each question:
Amount of money made = Base salary + (Amount sold × Commission percentage)
2)
17% = 0.17
0 + (37000 x 0.17)
6290
3)
6% = 0.06
10000 + (59000 x 0.06)
10000 + 3540
13,540
