Answer:
And as we can see on the plot we have the distribution left skewed so then this distribution is not normal because we don't have a bell shaped histofram and is not symmetric.
Explanation:
Assuming the following dataset
Temperature (F) Frequency
50-54 2
55-59 0
60-64 4
65-69 12
70-74 7
75-79 5
80-84 1
For this case we can construct the histogram with the following R code.
f<-c(2,0,4,12,7,5,1)
> barplot(f)
And the result is on the figure attached.

Answer:
a = 7.75 [m/²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
x = final distance = 190 [m]
Xo = initial distance = 0
Vo = initial velocity = 0 (car starts from the rest)
a = acceleration [m/s²]
t = time = 7 [s]
190 = 0 + (0*7) + 0.5*a*(7²)
190 = 0.5*49*a
a = 7.75 [m/²]
