1. Meet the Runkles: Harry and Marcia. The Runkles have two boys, Brian and Terry. Brian turns 11 years old in 2020 and starts secondary school in (2021) while Terry is a year younger and starts the year after (2022). The Runkles’ neighbours send their children to a private school. It costs $10,000 p.a. for year 7 and increases at a rate of 15 percent p.a. for years 8, 9, 10, 11 and 12. If, instead of sending Brian and Terry to the private school, they send them to the public school for a total cost of $10,000 each across all years, how much will the Runkles have saved by the end of 2027, when Terry would finish up? [Note: this is not a time value question. Simply add up the differential].

QUESTION 14

1. In a cross between AaBb x AaBb, roughly 50% of the offspring show the recessive phenotype and 50% show the dominant phenotype.  This indicates that:

   		crossing over has occurred
   		dominance is incomplete
   		the two genes are on the same chromosome
   		homozygous recessive is lethal

   QUESTION 15

Enacted in 1998, the Children’s Online Privacy Protection Act requires firms to obtain parental consent before tracking the information and the online movement of children; however, the act applies to those children ages 12 and under. Teenagers are often oblivious to the consequences of sharing their lives online. Data reapers create huge libraries of digital profiles and sell these profiles to advertisers, who use it to detect trends and micro-target their ads back to teens. For example, a teen searching online for ways to lose weight could become enticed by an ad for dietary supplements, fed into his/her network by tracking cookies. As a preliminary step in gauging the magnitude of teen usage of social networking sites, an economist surveys 200 teen girls and 200 teen boys. Of teen girls, 166 use social networking sites; of teen boys, 156 use social networking sites.

In a report, use the sample information to

1. Construct a contingency table that shows frequencies for the qualitative variables Gender (male or female) and Use of Social Networking Sites (Yes or No).

2. Determine the probability that a teen uses social networking sites.

3. Determine the probability that a teen girl uses a social networking site.

4. A bill before Congress would like to extend the Children’s Online Privacy Protection Act to apply to 15-year-olds. In addition, the bill would also ban Internet companies from sending targeted advertising to children under 16 and give these children and their parents the ability to delete their digital footprint and profile with an “eraser button” (The Boston Globe, May 20, 2012). Given the probabilities that you calculated with respect to teen usage of social networking sites, do you think that this legislation is necessary? Explain.

A recent census asked respondents to state the highest level of education that they had received. The responses were 39% High school, 45% TAFE or Undergraduate Degree, 13% Higher Degree and 3% Other.

The mayor of a small country town held a similar survey. Below are observed counts for each of the education levels for 250 respondents from the town: Highest Education Level

a) If the counts observed for the town matched that of the census, what would be the expected counts for

each education level?

b) To see if these results are unusual, should you perform a goodness-of-fit test or a test of independence?

c) State your hypotheses.

d) How many degrees of freedom are there?

e) Find x² and the P-value.

f) State your conclusion (use α = 0.05) in the context of the question.
