Directions: Solve the following problems carefully. After solving for the r-value find alsoa.) slope of the regression line, b.) the intercept of the regression line, c.) the general equation for simple regression, d.) graph the regression line. ( 15 pts each).

1. The average normal daily temperature ( in degree Celsius) and the corresponding average monthly precipitation( in inches ) for the month of June are shown below for seven randomly selected cities. Compute for the value of r, complete the table with the needed information.

Temperature(x)	30	27	28	32	27	23	18
Precipitation(y)	3.4	1.8	3.5	3.6	3.7	1.5	0.2

2. A law enforcement officer obtained data on the performance rating of the police offices and the crime solution efficiency in their respective areas of responsibilities for the last 6 months. The data are shown below, find the value of r by completing the table.

Performance rating (x)	85	89	91	93	84	89
Crime rate(y)	89	90	92	92	88	90
