Use the following description to answer questions 1, 2, and 3. A business manager wanted to know if there was a relationship between daily temperature measured in degrees Fahrenheit and number of employees who called-in sick each day. He collected the following data over 10 days:

Daily Temperature: 52 61 67 51 57 69 51 67 67 70

#Called-in Sick: 33 32 30 37 34 28 31 27 31 26

1. A. Obtain the mode, median, and mean for Daily Temperature only.

B. Obtain the range for Daily temperature.

C. Find the standard deviation for Daily temperature.

D. Provide an interpretation for your answer to part C.

E. What is the z-score for the daily temperature of 52? F. Provide an interpretation of the z-score obtained in part E.

G. What percentage of temperatures are expected to be in the range z = -.2 to z = +1.9? H. Obtain a histogram with four intervals for the Daily Temperature data only.

2. a. Find the value of the correlation coefficient (r) for Daily Temperature and # Called-in Sick.

b. State the null hypothesis for the problem described. (Be sure to use the variables given in the problem.)

c. Conduct a statistical test of the null hypothesis using p = .05. Be sure to properly state your statistical conclusion.

d. Provide an interpretation of your statistical conclusion given in part C.

e. What is the value of the coefficient of determination?

f. Provide an interpretation of your answer to Part E.

It has often been suggested that elements in our environment can provide cues for recalling past information. For example, a hypothetical study examined the effect of a specific perfume scent on students’ abilities to recall a set of objects. A random sample of 18 subjects was randomly assigned to one of two conditions: 1) Nine subjects memorized and then recalled a set of objects while a scent was present in the air. 2) The other nine subjects memorized and then...

Suppose a cognitive psychologist conducts a study on the effects of long-term substance use on short-term memory. The researcher recruits a total of 30 participants, where 10 participants are identified as marijuana users, 10 participants are alcohol users, and 10 participants identify as using no substances. Participants in each group were given a list of 20 nouns to memorize for 15 minutes. Participants were then given a 15- minute break and then asked to write down/recall as many of the...
