Alexandra Linder MATH 1710 Th 1:25 PM Exercises 1. 50 simulations in which a coin is thrown 100 times.
This histogram describing the number of times a head is thrown is unimodal-there is only one peak. It is not symmetrical. 2. a. One Bernoulli trial is a

I see the results are distributed between 38 to 60 heads in a trail. The most heads in a trail was
51 heads, which occurred about 8 times. The trails usually ended with 46 to 54 heads in a trail.

1. Testing a chip can be considered a Bernoulli trail, because it is possible to set up an
experiment whose outcome whose outcome is random and can be categorized into two
possible outcomes, success or failure of having a computer chip that

Case I: Lyme Disease
1.
Only one of the ticks carried the disease. There are 20 ticks so that is 1/20 or 5% of the
sample that was collected. The population probably does not have exactly the same
percentage as this sample, since the sample

e) Strong seasonal pattern with low consistent ozone concentrations in later summer/early fall and
high variable concentrations in early spring. The medians follow a cyclic pattern, rising from January
to April, then falling to October and rising again fr

a ) Let X1 , , Xn be a simple random sample where E[X1 ] = and V[X1 ] = 2 . Let X = n n Xi ,

then E[X ] = and V[X ] = n . Therefore, in this case E[X ] = 17 and V[X ] = 16 . Thus,
SD(X ) = 12 = 3.

I believe the medium is about 65 since it numeric value separating the higher half
of the sample from the lower half.
I made this estimate by mentally picturing in my head where the right sides and
left sides would appear kind of equal.
