Elisondra is eating at a restraurant with three friends. They want to choose at random who will order first. If you model the si

trapecia [35]

An equal-sized spinner is used to model probabilities

The spinner should have 4 equal sections

The number of friends is given as:

$\mathbf{Friends = 3}$

When Elisondra is included, the total number of people that went to the restaurant is:

$\mathbf{n = Friends + 1}$

Substitute 3 for Friends

$\mathbf{n = 3 + 1}$

Add 3 and 1

$\mathbf{n = 4}$

The number of people that went to the restaurant is the number of equal sections of the spinner.

Hence, the spinner should have 4 equal sections

A map of a park says its scale is 1 to 100. What does that mean?

Alex777 [14]

A scale is a term that refers to the representative fraction for comparing the original length and image length of a given object. It means implies that every 1 unit on the drawing is equal to 100 units on the park.

A scale is a term that can be referred to as the representative fraction that compares the original length and image length of a given object. Types of scale include enlarged scale, reduced scale, and real scale.

Enlarged scale is a scale that is used when the size of a given object is to be increased.
Reduced scale is used when the size of a given object is to be decreased.
Real scale implies the exact size of a given object.

Scale can be expressed as;

Scale = $\frac{length on drawing}{original length}$

Thus a scale has no unit.

Therefore, the given question implies that every 1 unit on the drawing is equal to 100 units on the original park. Thus it is a reduced scale.

1. IQ scores of statistics students have a standard deviation less than 15. A. H0:σ≤15, H1:σ>15 B. H0:σ≥15, H1:σ<15 C. H0:

grandymaker [24]

Answer:

1) For this case we want to check if the population deviation is less than 15( alternative hypothesis) and the system of hypothesis are:

H0: $\sigma \geq 15$

H1: $\sigma$

B. H0:σ≥15, H1:σ<15

2) For this case we want to check if the population mean $\mu$ is at most 70000 (alternative hypothesis) and the system of hypothesis are:

H0: $\mu \geq 70000$

H1: $\mu$

C. H0:µ≥70,000, H1:µ<70,000

3) For this case we want to check if the population proportion $p$ of all internet users that make online purchases is higher than 0.5 (alternative hypothesis) and the system of hypothesis are:

H0: $p \leq 0.5$

H1: $p >0.5$

D. H0:p≤0.5, H1:p>0.5

Step-by-step explanation:

Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

Solution to the problem

1) For this case we want to check if the population deviation is less than 15( alternative hypothesis) and the system of hypothesis are:

H0: $\sigma \geq 15$

H1: $\sigma$

B. H0:σ≥15, H1:σ<15

2) For this case we want to check if the population mean $\mu$ is at most 70000 (alternative hypothesis) and the system of hypothesis are:

H0: $\mu \geq 70000$

H1: $\mu$

C. H0:µ≥70,000, H1:µ<70,000

3) For this case we want to check if the population proportion $p$ of all internet users that make online purchases is higher than 0.5 (alternative hypothesis) and the system of hypothesis are:

H0: $p \leq 0.5$

H1: $p >0.5$

D. H0:p≤0.5, H1:p>0.5
