Answer:
[ 5.456, 5.544]
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 5.5 ounces
Standard deviation r = 0.2 ounces
Number of samples n = 80
Confidence interval = 95%
z value (at 95% confidence) = 1.96
Substituting the values we have;
5.5+/-1.96(0.2/√80)
5.5+/-1.96(0.022360679774)
5.5+/-0.043826932358
5.5+/-0.044
= ( 5.456, 5.544) ounces
Therefore the 95% confidence interval (a,b) = ( 5.456, 5.544) ounces
Answer:
50 cents per lollipop
Step-by-step explanation:
The full bag of lollipops costs 5.99 for 12 lollipops. You must use proportions.
5.99. _ X
———. ——
12. 1
Cross multiply to get 5.99 = 12x. Isolate the variable (x) by dividing by 12. 5.99/12 = 0.499166666666667
Because it is a price, round to the nearest hundredth and it costs about 50 cents per lollipop
<h2>They mark-up the price by <u>$13.20</u></h2><h3>The new price is $79.20 (If you need that information)</h3><h3><u /></h3><h3>66 x 0.20 = 13.20</h3><h3>The new price:</h3><h3>13.20 + 66 = 79.20</h3><h3 /><h3><em>Please let me know if I am wrong.</em></h3>
