Question
At this resolution level of the data, each dot in
the above graph represents about 200 Tesla
Model S EVs (Electric Vehicles) produced prior
to March 2017. Assuming there are 800 dots
on the graph for a total of 160,000 produced,
about 8 dots appear below 90% Remaining
Range level. So the probability of a
substandard battery is 1%.

What is the mean number of failures µ, ?
Sketch and label µ±30:
Hj =.
What is the standard deviation, o, of the
number of cars produced ?
(From Chapter 9) How many future random samples would be needed to make a 99% confidence interval (
Bound = .01) if the substandard rate has jumped to 2% ? Does this meet the minimum number of samples
required meet the basic conditions for a reasonable approximation of p ? If not, how many samples should be
taken ? Show this mean shift in your above sketch.
