The length of rose stems follows a normal distribution with a mean length of 19.15 inches and a standard deviation of 3.044 inches. A flower shop sells roses as parts of wedding flowers, wedding bouquets, and corsages. Please use this information to answer the following questions and please use R (not the z-table) for any calculations. a. What is the probability that a given rose stem will be shorter than 16.2 inches? Answer: Round to at least FOUR digits after the decimal if necessary. b. Suppose a rose is considered a 'long stem rose' if its stem length is longer than 24 inches. What is the probability that a given rose will be considered a long stem rose? Answer: Round to at least FOUR digits after the decimal if necessary. c. The flower shop has a rule that shortest 5% of roses are clipped and used as corsages. What is the maximum stem length (in inches) a rose can be and still qualify to be used as a corsage by the shop? Answer: inches. Round to at least FOUR digits after the decimal if necessary.

The length of rose stems follows a normal distribution with a mean length of 19.15 inches and a standard deviation of 3.044 inches. A flower shop sells roses as parts of wedding
flowers, wedding bouquets, and corsages. Please use this information to answer the following questions and please use R (not the z-table) for any calculations.
a. What is the probability that a given rose stem will be shorter than 16.2 inches?
Answer: Round to at least FOUR digits after the decimal if necessary.
b. Suppose a rose is considered a 'long stem rose' if its stem length is longer than 24 inches. What is the probability that a given rose will be considered a long stem rose?
Answer: Round to at least FOUR digits after the decimal if necessary.
c. The flower shop has a rule that shortest 5% of roses are clipped and used as corsages. What is the maximum stem length (in inches) a rose can be and still qualify to be used as
a corsage by the shop?
Answer:
inches. Round to at least FOUR digits after the decimal if necessary.
d. Suppose the z-score (standardized score) of a rose stem length given as 1.3. Which of the following statements is a correct interpretation of the meaning of this value?
A. The length of this stem is 1.3 inches longer than the average rose stem
B. The length of this stem is 1.3 standard deviations longer than the average rose stem
C. The length of this stem is 1.3 times longer than the average rose stem
D. There is not enough information provided to interpret this value
