Question

Hello, for this I had a question about what the homework help practice is talking about when saying to look for the P(X < 6.8), and to use technology in order to do so, I keep seeing questions like these popping up asking for the value of the x probability and not sure what would that mean or how  would I look for that value in the first place?

Over roughly the past 100 years, the mean monthly April precipitation in Williamstown, Massachusetts, equaled 3.6 inches with a standard
deviation of 1.6 inches. Complete parts a through c.
6.8 inches"? Select the correct choice below and fill in the answer box(es) to complete your choice.
A. P(X> )
(Type an integer or a decimal. Do not round.)
B. P(X< 6.8)
(Type an integer or a decimal. Do not round.)
C. P( <x< )
(Type integers or decimals. Do not round.)
While either technology or the by-hand method can be used to find this percentile, for the purposes of this explanation, use technology.
Use technology to determine the probability P(X<6.8). Since an x-value is being entered, be sure to update the values for the mean and
standard deviation in technology to use the given mean and standard deviation.
