Answer: It would cost Madison $7 to go for a 3-mile ride.
Step-by-step explanation:
Initial fee: $2.50
Per mile: $1.50
Set up an equation where = the number of miles driven
Using y = mx + b form:
y = 1.5x + 2.5
How much would a taxi ride cost if Madison is riding for 3 miles?
Simply plug in 3 for x
y = 1.5(3) + 2.5
y = 4.5 + 2.5
y = 7
Therefore, It would cost Madison $7 to go for a 3-mile ride.
How much would a taxi ride cost that is mm miles long?
To solve this plug in the number of miles driven for x and then solve
Answer:
Step-by-step explanation:
Data given and notation
represent the sample mean
represent the sample standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the true mean is different from 7.1 ppm, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
If we analyze the size for the sample is < 30 and we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(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".
Calculate the statistic
We can replace in formula (1) the info given like this:
