Taylor Swift wants to know the proportion of her fans who listened to her new single ME! within the first hour of it being relea

lara31 [8.8K]

Answer:

The parameter is the population proportion of fans who listened to her new single and has an estimated value of 90%.

Step-by-step explanation:

The parameter is a value that corresponds to a population, while an a value that corresponds to a sample is know as statistic.

She takes a sample to estimate, with a point estimate and probably with a confidence interval around this point estimate, the true proportion of fans who listened to her new single.

This is the paramater: the population proportion of fans who listened to her new single.

Its value comes from an estimation based on the sample proportion (point estimate).

The sample proportion is 90%, so we can estimate, as there is no bias, that the population proportion is also 90%.

Assuming boys and girls are equally likely, find the probability of a couple having a baby girl when their sixth child is born

Ivanshal [37]

Answer: The required probability of having 6th girl is 0.5.

Step-by-step explanation: Given that boys and girls are equally likely.

We are to find the probability of a couple having a baby girl when their sixth child is born, given that the first five children were all girls.

Since the events of having a boy and a girl are independent of each other, so

the probability of having 6th girl dose not depend on the birth of the first five girls.

We know that there are only two possible cases (either a boy or girl will born).

So, sample space, S = {G, B} and the event E of having a girl is, E = {G}.

That is, n(S) = 2 and n(E) = 1.

Therefore, the probability of event E is given by

$P(E)=\dfrac{n(E)}{n(S)}=\dfrac{1}{2}=0.5.$

Thus, the required probability of having 6th girl is 0.5.

Which of the following is a geometric sequence?

Maslowich

Answer: D

Step-by-step explanation:

As you can see it is switch from -3 to 3.

Why?

Because each time it is being multiplied by -1 so it switches from negative to positive and geometric sequences involve multiplication (and division so technically it could be dividing by -1).

How to solve this using probability

Fudgin [204]

To solve this using probability simply count the shapes that have at least 4 sides, and represent it as a fraction among all shapes in the spinner.

P(4 sides) = 5/6.
P(tails) = 1/2.

Both are independent events and as such must be multiplied with each other.

5/6 • 1/2 = 5/12,

This is the combined probability of both events occurring.
