A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If Greg chooses one marble at random 300 ti
dusya [7]

Answer:

60 times

Step-by-step explanation:

There are 6+4+3+2=15 marbles in total. Out of those, 3 are blue, so the probability of pulling a blue marble is \frac{3}{15}=\frac{1}{5}. However, this is only the probability of pulling a blue marble when 1 marble is pulled at random. Therefore, we can expect a blue marble to be pulled \frac{1}{5}*300=60 times if 1 marble is pulled 300 times at random. Hope this helps!

Solution for 11m-8m=
slavikrds [6]
You would have no trouble at all if the problem said "11 cows - 8 cows",
or "11 books - 8 books", or "11 cats - 8 cats", or "11 footballs - 8 footballs".

So why does it scare you when the items being counted are 'm's ?

Oh !  Here's another beauty:  11 M&Ms - 8 M&Ms = ?

Find the P-value for the hypothesis test with a standardized test statistic z. Decide whether toreject the null hypothesis for t
iren2701 [21]

Answer:

1.) We don't reject the null

2.) We reject the Null

3.) We do not reject the null

Step-by-step explanation:

Obtaining p values using test statistic:

Given that ; we have a standardized test statistic and α - values ;

Let's define the decision region :

If Pvalue < α ; Reject H0 ; otherwise, fail to reject H0

A.)

Left tail , Z = - 1.32 ; α = 0.10

We can use the Pvalue calculator from Z score :

Pvalue = 0.934

Pvalue > α ; Hence, we fail to reject the null, H0

B.)

Right-tailed test, z = 2.46, α = 0.01

Pvalue from Zscore calculator ;

Pvalue = 0.0069

Pvalue < α ; Hence, we reject the null, H0

C.)

Two-tailed test, z = -1.68, α = 0.05

Pvalue from Zscore calculator ;

Pvalue = 0.093

Pvalue > α ; Hence, we fail to reject the null, H0
