The type of distribution
From the given data, we have:
--- Mean and Median are not equal
and
--- Median is greater than mean
<em>When the median is greater than the mean; the histogram is expected to be left skewed</em>

Answer:
2.65secs
Step-by-step explanation:
Give:
The function h(t)=−16t(t−7) models
the object will hit the ground at h= 0
h(t)=−16t(t−7)
0= -16t(t−7)
0= -16t^2 + 112
16t^2 = 112
t^2 = 7
t= √7
t=2.65secs
Hence, the object object hit the ground at 2.65secs
