Are these values outliers? Explain. Any observations smaller than 8.3 Incorrect: Your answer is incorrect. % or larger than 13.5 Incorrect: Your answer is incorrect. % are considered outliers. Therefore, Oregon's data value (8.3%) Correct: Your answer is correct. an outlier and Mississippi's data value (13.5%) Changed: Your submitted answer was incorrect. Your current answer has not been submitted. an outlier. (b) Construct a boxplot for this data set. Comment on the interesting features of the plot. The boxplot shows Incorrect: Your answer is incorrect. and the distribution is . The minimum value is %, the lower quartile is %, the median is %, the upper quartile is %, and the maximum value is %.

The read efficiency is the percentage of times a data page is found in the data cache memory (or buffer pool) without requiring a physical I/O. How do you trace the read efficiency records and what factors impact this percentage?

The price elasticity of demand for bread
A. is computed as the percentage change in quantity demanded of bread divided by the percentage change in price of bread.
B. will be higher if there is a new product that is a close substitute for bread.
C. will be higher if consumers consider bread to be a necessity.
D. All of the above are correct.
E. A and B, only

Which of the following statements is (are) correct?
(x) The demand for strawberry ice cream is more elastic than the demand for ice cream because there are more substitutes for strawberry ice cream than ice cream.
(y) Insulin for insulin-dependent diabetics tends to have an inelastic demand because there are not many close substitutes for insulin and insulin is considered by some to be a necessity
(z) If a good is a luxury, demand for the good would tend to be elastic and the demand curve for the good would tend to be relatively flat.
A. (x), (y) and (z)
B. (x) and (y) only
C. (x) and (z) only
D. (y) and (z) only
E. (y) only

Which of the following statements is (are) correct?
(x) If a good is a necessity, demand for the good would tend to be inelastic and the demand curve for the good would tend to be relatively steep.
(y) Mac says that he would buy one apple pie per week regardless of the price. If this is true then Mac's demand for apple pie is perfectly inelastic and the price elasticity coefficient of demand is equal to zero.
(z) The demand for Papa John’s pizza is not as elastic as the demand for pizza because there are more substitutes for pizza than Papa John’s pizza.
A. (x), (y) and (z)
B. (x) and (y) only

It's possible to estimate the percentage of fat in the body by measuring the resistance of the upper leg rather than the upper arm; the calculation is similar. A person's leg meas-ures 40cm between the knee and the hip, with an average leg diameter (ignoring bone and other poorly conducting tissue) of 12cm . A potential difference of 0.79V causes a current of 1.6mA .

What are the fractions of muscle and fat in the leg?

Write a program to record the GPAs of a class and find the percentage of students in each GPA. The program first allows the user to enter the number of students enrolled in the class, and then to enter the GPA of all students one by one. For each student, the input must be between 1 and 4 inclusively. Otherwise, the software displays a message as “Invalid number!” and asks for a new GPA for the same student

Note: you should trace the GPA list just once. So, you should use an array GPAFreq with four elements; to store the frequencies of each GPA from 1 to 4.
