A company publishes statistics concerning car quality. The initial quality score measures the number of problems per new car sold. For one year, Car A had 1.26 problems per car. Let the random variable X be equal to the number of problems with a newly purchased model A car. Complete (a) and (b) below.
a. If you purchased a model A car, what is the probability that the new car will have zero problems? The probability that the new model A car will have zero problems is :___ (Round to four decimal places as needed.)
b. If you purchased a model A car, what is the probability that the new car will have two or fewer problems? The probability that a new model A car will have two or fewer problems is :___ (Round to four decimal places as needed.)
Hope this helps you find your answer
Answer:
20
Step-by-step explanation:
Why? because 100$ in 5 days is he spent the same much each day then it's 20 because 20 x 5=100
20 x 1=20
20 x 2=40
20 x 3=60
20 x 4=80
20 x 5=100
Let x represent the scores. With mean and standard deviation given,
The Empirical rule states that
1) About 68% of the x values lie between 1 standard deviation below and above the mean
2) About 95% of the x values lie between 2 standard deviation below and above the mean
3) About 99.7% of the x values lie between 3 standard deviation below and above the mean
If we consider this rule, then the percentage of scores that fall within 3 standard deviation (-3 to +3) is 99% because this is closer to 99.7%
Nothing further can be done with this x=3a
