A random variable Y has a Weibull distribution with parameters α = 4 and β = 7.865. Look at a graph of this Weibull distribution using the excel spreadsheet. It looks somewhat bell-shaped. Note the mean and standard deviation provided to the left of the graph. Now, suppose we wished to use the normal curve to approximate P( 5.2 < Y < 9.1 ). Using a normal curve with the same mean and standard deviation as Y, find the area between 5.2 and 9.1.Express your answer as a proportion rounded to 4 decimal places.

A random variable Y has a Weibull distribution with parameters α = 4 and β = 7.865. Look at a graph of this Weibull distribution using the excel spreadsheet. It looks somewhat bell-shaped. Note the mean and standard deviation provided to the left of the graph.

Now, suppose we wished to use the normal curve to approximate P( 5.2 < Y < 9.1 ). Using a normal curve with the same mean and standard deviation as Y, find the area between 5.2 and 9.1.

Express your answer as a proportion rounded to 4 decimal places.
