Answer:
1. $441.75
2. $456.50
Step-by-step explanation:
Question 1:
9.5 × 40 = 385
Jim will earn $385 dollars from his regular without overtime every week (pretend that he did not get paid overtime from that week.)
Since he got 40 regular hours plus 6.5 hours for overtime, his pay from last week is $441.75
9.5 × 46.5 = $441.75
Question 2:
Since she has gotten over $5000 in sales from that week, she earned $456.50
8550 - 5000 = $3550
3% of 3550 = 106.5
$350 + $106.5 = $456.50
Her expected total earning from that week is $456.50
Answer:
a)
b)
c)
And the 90% confidence interval for the true proportion is given by (0.527;0.593).
Step-by-step explanation:
Part a
For this case we don't have any prior info given so then the probability assumed for this case is:
Part b
For this case the proportion of success is given by:
Part c
The confidence interval for the true proportion would be given by this formula
For the 90% confidence interval the value of and , and the critical value would be given by:
The confidence interval is given by:
And the 90% confidence interval for the true proportion is given by (0.527;0.593).
Let the unknown number be x
23-44x=199
23-199=44x
-176=44x
x=-4
