Answer:

1. Two friends Max and Mary are standing at the same spot in a garden. Max takes 5 steps backwards and then again 3 more steps backward. So, what is the current position of Max with respect to the spot where Mary is standing?

Solving this, we know that if the initial spot is assumed to be zero, then first Max took 5 steps backwards that means -5 and then again 3 steps that gives -3.

So, we get total steps backwards as $(-5)+(-3)=-8$

Hence, Max is 8 steps backwards with respect to the spot where Mary is standing.

2. A basketball team played two games. In the first game the team lost 6 points and in the second game they lost another 6 points. What is the change in the score of the team after these two games?

We will solve this like $(-6)+(-6)=-12$

John owes 15 dollars to Bill, then another 2 dollars to Joey. How much money does John have?

Since John has 0 dollars to give, he has (-15)+(-2) =-17 dollars (as 15+2=17, so the same can be applied negatively) as the first 17 dollars he gets has to be given to Bill and Joey

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%.

(a) When you roll a dice, which number are you most likely to get?

(b) If you rolled a dice 600 times how my sixes would you expect to get?

Solution

(a) You are equally likely to get any of the six numbers.

(b) You would expect to get a six in about 1

of the throws, so 100 sixes.

Worked Example 2

Use one of the following to describe each one of the statements (a) to (d).

Certain

Very likely

Likely

Unlikely

Very unlikely

Impossible

(a) It will snow tomorrow.

(b) It will rain tomorrow.
