B) μD = 0.60 ± 0.10(1.397)
Step-by-step explanation:
The confidence interval is given by:
Where
MD=60
n=9
df=n-1=8
Then the confidence interval is
μD=0.60±1.397*(0.3/√9)
μD=0.60±0.10*(1.397)

Let x be marked up price. We have been given that a chemistry set costing $27.50, marked up 32% on cost.
Therefore, mark up price is $8.80.
Since we know that selling price of any item equals the sum of cost and mark-up price of the item.
Let us find selling price of our chemistry set.
Therefore, the selling price of the chemistry set is $ 36.30.
