Case 2  Your patient is a 36 year old female who works as a banker and has 3 school-aged children.  She smokes about three packs of cigarettes per week, occasionally drinks alcohol, and has a mild (managed) history of heart burn (reflux).  About 2 weeks ago she began to notice a change in her vocal quality and more recently has developed pain in her ear.  B). What are three laryngeal pathologies/voice disorders which this patient is at highest risk for developing? (3 points)

Case 1: (Video) A 45 year old male presents to your clinic with complaints of difficulty speaking for the past 5 years.  B). How would you describe this person’s glottal closure? (1 point).  What is one way you would perceptually describe this patient’s vocal quality? (1 point)

g. In a meeting explaining your results, the County Commissioner says “The results from your analysis seem to indicate that having access to universal child care has an effect on weekly wages.” How do you respond?

c. What is the degrees of freedom, only if appropriate, and the p-value?  

Submit your work from the previous question (ie hand calculation of the test statistic) as one file (either a picture of your written work or an upload of a word document showing your work). Note: this question is not marked as any points, but affects the grade from the previous question (allows me to confirm you did the work; allows me to award partial credit in the case of a small mistake).

d. Using alpha=.05, should you reject or fail to reject the null hypothesis? Why?

b. Construct a 92% confidence interval for the proportion supporting county-funded daycare. Input the lower and upper bounds of interval, rounding to two decimal places. You will have to submit your work for this and 3a in a question below.    Lower bound: [lower] Upper bound: [upper]

e. State your conclusion directly to the County Commissioner.

Given 30, 80, and 50, find the LCM. 

Estimate by rounding each addend to the hundreds place:
