Matt wants to purchase a gasoline motor scooter. The gas mileage 75 miles for each 1/2 gallon of gasoline. How many miles will M
Paraphin [41]

Answer: 750 miles

Step-by-step explanation:

The gas mileage is 75 miles per 1/2 gallon of gasoline.

First find how many miles it can go on 1 gallon of gasoline:

= 75 ÷ 1/2

= 150 miles

If the scooter can go 150 miles on 1 gallon, the number of miles it will go on 5 gallons is:

= 5 * 150

= 750 miles

One factor in rating a National Hockey League team is the mean weight of its players. A random sample of players from the Detroi
lukranit [14]

Answer:

1) Random: A random sample needs to be obtained in order to apply inference for the mean

2) Normality condition: The sampling distribution of \bar X needs to be approximately normal. If we use a random sample size higher than 30 we can use the Central Limit theorem to verify this condition.

3) Independence: All the individual observations need to be independent. And we need to satisfy that our sample would be lower than 10% of the real population size.

Step-by-step explanation:

For this case we need three conditions:

1) Random: A random sample needs to be obtained in order to apply inference for the mean

2) Normality condition: The sampling distribution of \bar X needs to be approximately normal. If we use a random sample size higher than 30 we can use the Central Limit theorem to verify this condition.

3) Independence: All the individual observations need to be independent. And we need to satisfy that our sample would be lower than 10% of the real population size.

Data given and notation  

\bar X=203 represent the sample mean

s=10.9 represent the sample standard deviation  

n=17 sample size  

\mu_o represent the value that we want to test  

\alpha=0.01 represent the significance level for the hypothesis test.  

t would represent the statistic (variable of interest)  

p_v represent the p value for the test (variable of interest)  

State the null and alternative hypotheses.  

We can assume the following system of hypothesis.

Null hypothesis:  \mu = \mu_o  

Alternative hypothesis :\mu\neq \mu_o  

The degrees of freedom on this case:

df=n-1=10-1

Compute the test statistic

The statistic for this case is given by:  

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}} (1)  

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".

Find four consecutive integers such that
shusha [124]

Answer:

1st= 1

2nd =2

3rd =3

4th = 4

Step-by-step explanation:

Let's make an equation.

1) x

2) x+1

3) x+2

4) x+3

2*[(x+1+x+2+x+3)-x]=16

2*[(3x+6)]-x]=16

2[2x+6]=16

4x+12=16

4x=4

x=1
