Answer:
The height on the map is of 12 inches.
Step-by-step explanation:
Scale of 1 inch:300 meters
This means that each inch on the map represents 300 meters of real height.
If the actual height of one of those mountains is 3,600 meters, what is its height on the map?
Using proportions, by a rule of three:
1 inch - 300 meters
x inches - 3600 meters
Applying cross multiplication:
The height on the map is of 12 inches.
Answer:
The degrees of freedom are given by:
The p value for this case is given by:
Since the p value is higher than the significance level of 0.06 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly less than 25.5 and then the claim makes sense
Step-by-step explanation:
Information given
represent the sample mean
represent the sample standard deviation
sample size
represent the value to verify
represent the significance level
t would represent the statistic (variable of interest)
represent the p value
Hypothesis to est
We want to test if the true mean is at least 26 mpg, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by;
(1)
Replacing the info given we got:
The degrees of freedom are given by:
The p value for this case is given by:
Since the p value is higher than the significance level of 0.06 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly less than 25.5 and then the claim makes sense
