Answer:
89
Step-by-step explanation:
<h2>How do you find the range of a data set?</h2><h3><u>first put you're data set from lowest to highest, then subtract your highest by your lowest value</u></h3><h3>Data:</h3>
8, 8, 12, 41, 64, 97
<u>We can clearly see that our highest value is 97, and our lowest in 8.</u>
<h3>97 - 8 = <u>89</u></h3><h2>Hence our range of data is 89.</h2>
Answer:
E(x) = 1.43 (Approx)
Step-by-step explanation:
Given:
Total number of camera = 7
Defective camera = 5
Sample selected = 2
Computation:
when x = 0
P(x=0) = 2/7 × 1/6 = 2/42
P(x=1) = [2/7 × 5/6] + [5/7 × 2/6] = 20/42
P(x=2) = 5/7 × 4/6 = 20/42
So,
E(x) = [0×2/42] + [1×20/42] + [2×20/42]
E(x) = 1.43 (Approx)
