7. The claim that started this investigation was that students majoring in engineering are more likely to be in the marching ban
Genrish500 [490]

Answer:

See explanation below.

P(M|E) > P(M|O)

Step-by-step explanation:

Notation

First we need to define the following events:

E = The student is in a major of enginnering

O= The student is in a major different from enfinnering

M= The student is in the marching band

Solution for the problem

For this case we can calculate the following probability:

P(M|E) =\frac{P(M and E)}{P(E)}

And that represent the following event: "Given a randomly selected student is an engineering major, what is the probability  the student is in the marching band"

And the probability that need to calculate to compare is this one:

P(M|O) =\frac{P(M and O)}{P(O)}

And that represent the following event: "Given a randomly selected student is NOT an engineering major, what is the probability  the student is in the marching band"

And if the claim is satisfied we need to see this:

P(M|E) > P(M|O)

Find the amount of sap the maple syrup producer collected from each tree if the total amount (5 gallons) was redistributed equal
Afina-wow [57]
The picture in the attached figure

we know that
total amount of sap =[3*(1/4)+2*(3/8)+4*(5/8)+1*(1)]
total amount of sap =[(3/4)+(6/8)+(20/8)+(1)]
total amount of sap =[(3/4)+(3/4)+(10/4)+(4/4)]
total amount of sap =[20/4]
total amount of sap =5 gallons
total of trees=10

<span>[amount of sap collected from each tree]=total amount of sap/total of trees
</span>
[amount of sap collected from each tree]=5/10----> 0.5 gallons per tree

the answer is
0.5 gallons

A study was done on the batting averages for two baseball players: Hitmore and Bunter. Data were collected over a period of time
amm1812

Answer:

Both (B) and (C) are correct

Step-by-step explanation:

Explaining in simple terms, The Simpson's paradox simply describes a phenomenon which occurs when observable trends in a relationship, which are obvious during singular evaluation of the variables disappears when each of this relationships are combined. This is what played out when hitmire appears to d well on both of natyraknamd artificial turf when separately compared, but isn't the same when the turf data was combined. Also, performance may actually not be related to the turf as turf may Just be. a lurking variable causing a spurious association in performance.
