HU Statistics Questions
Question 1A sample of nurses with
affiliation to private hospitals (affiliation = 0) and to university
hospitals (affiliation = 1) was asked to rate their confidence in making
the right decisions based on their level of ongoing inservice
professional development. Use a Mann-Whitney U-test to determine if the
distribution of confidence in each group is the same. The file is the
first tab in “nonparametric.xlsx.” Be sure to always write the
null and alternate hypotheses, so that the decision is made in the
correct direction. Also, conduct all as two-tailed tests at α = 0.05.Question 2In
the previous item, we used the Mann-Whitney test rather than an
independent t-test. Why might we Mann-Whitney rather than the t-test?Question 3
In the third tab of the same file (nonparametric_sheets.xslx), there
are data for the selling prices of homes in a ZIP code and the square
footage of those homes. Use the Spearman rank correlation to determine
if there is a significant correlation between the home price and the
square footage.A table of Spearman rank significance values is located in the file. Question 4Why
did we not just use the Pearson correlation for the previous item? That
is, what is the Pearson correlation influenced by that the Spearman is
not?Question 5A restaurant wondered if
there was a difference in the number of refills of soda ordered by those
aged 18-24 (age = 0) and those aged 13-17 (age = 1). Use the
Mann-Whitney U-test to determine if the distribution of soda refills is
significantly different for the two groups.Question 6An
organization was attempting to determine whether there was congruence
between the rating of their hiring personnel in rating new employees
during their interview presentations. The file “Spearman 2” to determine
the Spearman rank correlation between the judges’ ratings.Question 7The following data were collected related to the number of visits to a suburban health clinic. Month Visits January 1610 February 1585 March 1649 April 1590 May 1540 June 1397 July 1410 August 1350 September 1495 October 1564 November 1602 December 1655 The
null hypothesis is that the number of visits is uniformly distributed
throughout the year. Use a chi-square goodness-of-fit test to determine
whether the null hypothesis should be rejected at α = 0.05. Interpret
the results.Question 8There are 8 job
codes in a large hospital system. The table below indicates the number
of grievances filed by members of the union by job code. Are the number
of grievances uniformly distributed at α = 0.05? Job Code Grievances 1 19 2 17 3 14 4 18 5 19 6 21 7 18 8 18 Interpret this for hospital leadership.Question 9A
research firm was interested in knowing whether income level and
location of service for procedures were independent. The following data
were provided. Clinic Hospital Private <$30,000 85 16 6 $30,000 to $49,999 102 27 13 $50,000 to $99,999 36 22 15 > $99,999 15 23 25 Use
a chi-square test of independence to determine whether income level and
service location are independent. Test the null hypothesis the service
location is independent of income at α = 0.01.Question 10Is
the preferred beverage ordered at lunch independent of the age bracket
in a hospital cafeteria? Test the null that is independent at α = 0.05. Coffee/Tea Soft Drink Other 21-34 26 95 18 35-55 41 40 20 >55 24 13 32

The Language of Algebra
Learning some basic definitions in the language of algebra will give you the framework you need. The terms in the two original questions are 5 and 2, and the operation is adding in the first expression and multiply¬ ing in the second. The 5 and 2 are specific numbers. But in algebra, the terms can be variables, a key word based on “to vary” or “to change.” If you change 5 + 2 = 7 (which you know is true) to x + 2 = 7, you’ve created an equation that may or may not be true, depending on the value of the variable x.
