A researcher wishes to see if there is a relationship between the number of reported cases of measles and mumps for a recent 5-year period. Is there a linear relationship between the two variables?

Measles Cases	47	137	67	59	205
Mumps Cases	1655	620	2047	2556	363

(A) Draw the scatter plot for the variables.

(B) Compute the value of the correlation coefficient. c) State the hypotheses.

H0: =0

H1:0

(d) Test the significance of the correlation coefficient at =0.05, usingLos valores crticos para la tabla coeficiente de correlacin del producto-momento.

(e) Give a brief explanation of the type of relationship.
