Suppose the amounts of M&M's a machine dispenses into packages has a normal distribution with a mean of 25 M&M's and a standard deviation of 1 M&M. What is the probability that there are more than 26 M&M's?

16%

Step-by-step explanation:

The mean is 25, and the standard deviation is 1.

26 is 1 standard deviation above the mean.

According to the empirical rule, 68% of the population is between -1 and +1 standard deviations.  That means that 32% is less than -1 or greater than +1 standard deviations.  So half of that, or 16%, is greater than +1 standard deviations.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
