The information provided will allow us to create a ratio of the number of fliers given out on Wednesday in relationship/compared to the total number of flyers. This would be written as 99 on Wed./250 total. I found this by reading the question. It asked for the fraction given out Wed., which we can write a ratio of part to total for. The part is Wednesday and total is all the days added together.
Answer:
Step-by-step explanation:
If you add up all the male and female categories, the total is 400
the number of females between 22 and 39 is 51
P(22 - 39) = 51 / 400
P(22 - 39) = 0.1275
I think the answer you want is 51/400
Rotating a figure 90° counterclockwise about the origin results in an ordered pair (x, y) mapping to its image (-y, x). Thus point C, which is at (3, 5), will map to (-5, 3).
Answer:
The p value would be given by this probability:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and then we can conclude that the true mean is not significantly different from 29.1 MPG
Step-by-step explanation:
Information given
represent the sample mean
represent the population standard deviation
sample size
represent the value to verify
represent the significance level
t would represent the statistic
represent the p value
Hypothesis to test
We want to verify if the true mean is equal to 29.1 MPG, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info:
The p value would be given by this probability:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and then we can conclude that the true mean is not significantly different from 29.1 MPG
