Can you solve 15, 16,17,18, and 19 but also explain how you got your answers. Also use the standard normal distribution table I would greatly appreciate it ?
The average monthly mortgage (house) payment is $982 in a certain geographical
area. If the payments are normally distributed with a standard deviation of $180,
find the following probabilities.
16. A randomly selected house payment is more than $1000.
17. A randomly selected house payment is more than $1450.
18. A randomly selected house payment is between $800 and $1150.
19. Your house payment is $750 per month. How does this compare to the other house
payments in your area? What factors need to be considered when looking at house
payment data?
Bonus
The average charity contribution is $592. If charity contributions are normally distributed
