900 divided by 3 is 300 so 300 students bring their lunch opposed to 600 students who do not.
Answer:
0.2061
Step-by-step explanation:
Probability (no crash) = 66% = 0.66
Average (no crash) expected out of 152 computers = 0.66 (152) = 100.32
Standard deviation 's' = √ [ (154) (0.66) (1-0.66) ] = √ (154) (0.66) (0.34)
= √ 34.5576 = 5.87
P (x <u>></u> 96) = 1 - P (x <u><</u> 95)
z= (x - u) / s ; x = sample mean = 95.5 (continuity correction factor = 0.5) , u = population average = 100.32
z = (95.5 - 100.32) / 5.87 = 4.82 / 5.87 = 0.82
P (x <u><</u> 95) = P (z <u><</u> 0.82) = 0.7939
P (x <u>></u> 96) = 1 - 0.7939 = 0.2061
