Part 2

I used the Crime Dataset.

my.dat <- read.csv("Crime_Data.csv")
str(my.dat)

After running a structure command, I found 2 observations with missing Occured.Time and Reported.Time variables. Since I do not know when these specific crime observations occurred and reported, I cannot alter these NA values.

Part 3

As part of my experiment, I will set exercise times three times a week, and also set a fixed sleeping schedule. I expect to see my daily step count, water intake, and reported mood levels to change as a result of the intervention.

Hypothesis: Running 3-4 times a week will increase my average step count, water intake, and increase my mood level.
