Question 1
The speed at which an automated assembly line produces a product follows a normal distribution, with a mean production time of 32.20 seconds and a standard deviation of 1.05 seconds. What is the probability that a product requires more than 34 seconds to produce?

Question 2
Three hundred college students are randomly selected and their height is recorded. To support a particular statistical analysis, the data set is tested for normality using the normal probability plot shown here. What conclusion is correct concerning this data set?
◦
The heights are not normal because the plot does not conform well to a linear pattern, but has a curvilinear pattern instead.
◦
The heights are normal because the plot does not conform well to a linear pattern, but has a curvilinear pattern instead.
◦
The heights are not normal because the pattern at a normal score of 0 is approximately linear (vertical).
◦
The heights are normal because the pattern at a normal score of 0 is approximately linear (vertical).
