Flavia was curious if a sample first quartile (or Q1) was an unbiased estimator of a population first quartile. She started with a large normally distributed population of test scores whose first quartile was Q1=70 points. She then took a random sample of 6 tests and calculated the first quartile of the sample. She replaced those tests and repeated this process for a total of 50 trials. Her results are summarized in the dotplot below, where each dot represents the first quartile from a sample of 6 tests. Based on these results, does sample first quartile appear to be a biased or unbiased estimator of population first quartile? Hint: The population first quartile is 70. Choose 1 answer: (4) Sample first quartile appears to be a biased estimator since it consistently underestimated the population first quartile. (0) Sample first quartile appears to be a biased estimator since it consistently overestimated the population first quartile. (c) Sample first quartile appears to be an unbiased estimator of the population first quartile.

During the 1980s, sales of compact discs surpassed record sales. From 1985 to 1990, sales of compact discs in millions can be modeled by the formula f(x)=48.6(x-1985)+8.5, whereas sales of LP records in millions can be modeled by g(x)=-29.2(x-1985)+45.3. Approximate the year x when sales of LP records and compact discs were equal by using the intersection-of-graphs method. Each had equal sales in the year (Round to the nearest whole number as needed.)

Determine whether the following statements are true and give an explanation or counterexample. a. All polynomials are rational functions but not all rational functions are polynomials. b. If f is a linear polynomial, then f o f is a quadratic polynomial. c. If f and g are polynomials, then the degrees of f ∘ g and g ∘ f are equal. d. To graph g(x)=f(x+2), shift the graph of f two units to the right. b. Choose the correct answer below. A. The statement is true. Let f(x)=ax+b be a linear function where a and b are constants. Then f ∘ f=(ax+b)(ax+b)=a^2 x^2+2abx+b^2. B. The statement is true. The degree of the composition function f ∘ g is the sum or the degrees of the functions f and g. If both functions are linear, the sum of their degrees is 2. C. The statement is false. Let f(x)=x+2. Then f ∘ f=f(f(x))=(x+2)+2=x+4. This is a linear function.
