According to the DuPont 2012 Global Automotive Color Popularity Report, 23% of all cars manufactured in 2012 were white. In a random sample of 100 cars parked in long-term parking at Philadelphia International Airport, 19% of the cars were white. Identify the underlined values as parameters or statistics and give the appropriate variable. Spell out phat, x-bar, mu, sigma for the variable names. Which of the following statements istrue?
a. 19% and 23% are parameters, 100 is a statistic.
b. 23% is a parameter, 19% is a statistic.
c. 23% is a statistic, 19% is a parameter.
d. 19% and 23% are statistics, 100 is neither a parameter nor a statistic.
e. 19%, 23%, and 100 are all statistics.
Answer:
b. 23% is a parameter, 19% is a statistic.
Step-by-step explanation:
If the value is from a population, it is a parameter.
Otherwise, if the value is from a sample, it is a statistic.
23% of all cars manufactured in 2012 were white.
This is from the population(all cars), so 23% is a parameter.
In a random sample of 100 cars parked in long-term parking at Philadelphia International Airport, 19% of the cars were white.
100 is the size of the sample, which is neither a parameter, nor a statistic.
19% is from the sample of 100, so it is a statistic.
The correct answer is given by option b.

Height:
cm
Height of prism is 20 cm
Calculation of rectangular prism:Given that;
Volume of rectangular prism = 1620 cm³
Length = 9 cm
Width = 9 cm
Find:
Height of prism
Computation:
Volume of rectangular prism = (l)(b)(h)
So,
(9)(9)(h) = 1620
(81)(h) = 1620

How do you find the sum of the first 10 terms?
To sum up the terms of this arithmetic sequence: a + (a+d) + (a+2d) + (a+3d) +
Example: Add up the first 10 terms of the arithmetic sequence:
a = 1 (the first term)
d = 3 (the "common difference" between terms)
n = 10 (how many terms to add up)
What is the sum of the first 10?
