2018, the Amazon Alexa app was downloaded some 2,800 times per day from the Google Play store (AppBrain website). Assume that th
number of downloads per day of the Amazon Alexa app is normally distributed with a mean of 2,800 and standard deviation of 860.
a. What is the probability there are 2,000 or fewer downloads of Amazon Alexa in a day (to 4 decimals)?
0.1761
b. What is the probability there are between 1,500 and 2,500 downloads of Amazon Alexa in a day (to 4 decimals)?
0.2982
c. What is the probability there are more than 3,000 downloads of Amazon Alexa in a day (to 4 decimals)?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
