Assume that we want to construct a confidence interval. Do one of the​ following, as​ appropriate: (a) find the critical value t

Subscript alpha divided by 2​, ​(b) find the critical value z Subscript alpha divided by 2​, or​ (c) state that neither the normal distribution nor the t distribution applies.
The confidence level is 95​%, sigma is not​ known, and the histogram of 60 player salaries​ (in thousands of​ dollars) of football players on a team is as shown.

Answer:

Neither the normal distribution nor the t distribution applies.

Step-by-step explanation:

Hello!

The histogram attached shows the salary (in dollars) of 63 football players.

As you can see most of the values of this distribution are around 0 and the distribution is extremely asymmetrical (right skewed).

To apply a t-test to study the population average the population has to have a normal distribution.

The same goes for the standard normal distribution, but in this case, considering that the sample is large enough (n≥30) you can apply the Central Limit Theorem and approximate the distribution of the sample mean to normal X[bar]≈N(μ;δ²/n), but since the population variance is unknown, this is also not applicable.

The correct choice is the last one, since the conditions to apply the t test and the standard normal are not met.

I hope this helps!

Katherine has 32 pop songs in 72 rock songs on her MP3 player that she will be organizing into paulista. Que want to por an eria
LUCKY_DIMON [66]

Answer: The greatest  number of playlist Katherine can make =8

Each of playlist will have 4 pop songs and 9 rock songs.


Step-by-step explanation:

Given: The number of pop songs Katherine has= 32

The number of rock songs Katherine has= 72

If she want to make playlist such that in each playlist there is equal number of pop and rock songs, we need to find the GCF(greatest common factor) of 32 and 72.

We know that 32=2\times2\times2\times2\times2\\72=2\times2\times2\times3\times3

We can see the GCF(32,72)=2\times2\times2=8

Hence, the greatest  number of playlist Katherine can make =8

The number of pop songs= \frac{32}{8}=4

the number of rock songs=\frac{72}{8}=9

Each of playlist will have 4 pop songs and 9 rock songs.
