The amount of coffee that people drink per day is normally distributed with a mean of 14 ounces and a standard deviation of 7 ounces. 35 randomly selected people are surveyed. Round all answers to 4 decimal places where possible.
- What is the distribution of XX? XX ~ N(__,__)
- What is the distribution of xx? xx ~ N(__,__)
- What is the probability that one randomly selected person drinks between 13.5 and 14.2 ounces of coffee per day?
- For the 35 people, find the probability that the average coffee consumption is between 13.5 and 14.2 ounces of coffee per day.
- For part d), is the assumption that the distribution is normal necessary? NoYes
- Find the IQR for the average of 35 coffee drinkers. Q1 =__ ounces Q3 =__ ounces IQR: __ ounces
- Please show to me the answer using the T1 84 calculator. Thank you.
