Return to the Pew Research Internet Project's May 2010 survey of 2,277 adults, aged 18 years and older.
State the null hypothesis for testing the correlation between the variable Age and the number of daily cell phone calls, Q18, "On an average day, about how many phone calls do you make and receive on your cell phone?"
State the alternative hypothesis.
Test the assumptions (linearity, normality) and underlying correlations using SPSS.
Be sure to create a scatterplot to show the relationship between the two variables.
State your conclusions relative to the assumptions.

What is the number of observations used for each variable?
How did you handle missing data?
What is the value of the Pearson correlation coefficient between these two variables? In SPSS, use Analyze/Correlate/Bivariate.
Do you accept or reject your stated null hypothesis at the 0.01 level of significance?

Computer Lab: Hypothesis Testing Co
elations
For this assignment, you will test the co
elation between two variables from a cell phone usage
survey and prepare a report on your findings. Complete the following:
 Return to the Pew Research Internet Project's May 2010 survey of 2,277 adults, aged 18
years and older.
 State the null hypothesis for testing the co
elation between the variable Age and the number
of daily cell phone calls, Q18, "On an average day, about how many phone calls do you
make and receive on your cell phone?"
Null Hypothesis: H0: ρ = 0
That is, there is no significant relationship between Age and the number of cell phone calls
Alternate Hypothesis: Ha: ρ ≠ 0
That is, there is a significant relationship between Age and the number of cell phone calls
 Test the assumptions (linearity, normality) and underlying co
elations using SPSS.
Kolmogorov – Smirnov test is used to check the normality assumption
Tests of Normality
Kolmogorov-Smirnov

Shapiro-Wilk
Statistic df Sig. Statistic df Sig.
Q18. On an average day,
about how many phone calls
do you make and receive on
your cell phone?
.454 1917 .000 .232 1917 .000
AGE. What is your age? .049 1917 .000 .978 1917 .000

From the above table, we see that the p – value of Kolmogorov-Smirnov test is less than
0.05, indicating...
