10 weeks
Duane adds $5 every other week so that's 5 weeks out of 10. 5 x 5 = 25
Mick adds $2 every week so,
2 x 10 = 20
25 + 20 = 45
The answer is 8/5 which also matches quizlet
68.2 % of the data is within one σ, either side of the mean
95.4 % of the data is within two σs, either side of the mean
99.7 % of the data is within three σs, either side of the mean
Therefore, 0.3 % of values lie outside the range of value of three σs.
We can say this is representative of the chance that a value (in this case, the lifetime of the fan) will exceed the mean value by more than three σs.
