Biography

I am a Mathematical Economics student enrolled in Temple University's honors program. In the past, I taught private clarinet and saxophone lessons for about 4 years; during my time, all 17 of my students were members of his or her school's select honor bands. As far as content knowledge and a practical application of skills go, I have been an intern at the Bureau of Labor Statistics, have co-authored multiple conference presentations, where my main role has been statistical analysis and data visualization, and am currently interning at the Federal Reserve Bank of Philadelphia's research department. I hope I can share my knowledge and help students achieve better opportunities through being a Numerade educator.

Essentials of Modern Business Statistics

During the $2007-2008 \mathrm{NCA}$ A college basketball season, men's basketball teams attempted an all-time-high number of 3 -point shots, averaging 19.07 shots per game (Associated
Press Sports, January $24,2009 ) .$ In an attempt to discourage so many 3 -point shots and encourage more inside play, the NCAA rules committee moved the 3 -point line back from
19 feet, 9 inches to 20 feet, 9 inches at the beginning of the $2008-2009$ basketball season.
Shown in the following table are the 3 -point shots taken and the 3-point shots made for a
sample of 19 NCA basketball games during the $2008-2009$ season.
a. What is the mean number of 3-point shots taken per game?
b. What is the mean number of 3-point shots made per game?
c. Using the closer 3 -point line, players were making 35.2$\%$ of their shots. What percentage of shots were players making from the new 3 -point line?
d. What was the impact of the NCAA rules change that moved the 3 -point line back to
20 feet, 9 inches for the $2008-2009$ season? Would you agree with the Associated
Press Sports article that stated, "Moving back the 3 -point line hasn't changed the game
dramatically"? Explain.

Essentials of Modern Business Statistics

Because of high production-changeover time and costs, a director of manufacturing must convince management that a proposed manufacturing method reduces costs before the new method can be implemented. The current production method operates with a mean cost of $\$ 220$ per hour. A research study will measure the cost of the new method over a sample production period.
a. Develop the null and alternative hypotheses most appropriate for this study.
b. Comment on the conclusion when $H_{0}$ cannot be rejected.
c. Comment on the conclusion when $H_{0}$ can be rejected.
