Answer:
Now we can calculate the p value with this probability:
Since the p value is higher than the significance level provided of 0.1 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean for this case is higher than 31.1MPG using a significance level of 10%. So then the cliam makes sense
Step-by-step explanation:
Information given
represent the sample mean
represent the population deviation
sample size
represent the value to verify
represent the significance level
z would represent the statistic
represent the p value
Hypothesis to test
We want to check if the true mean for this case is higher than 31.1 MPG, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Since we know the population deviation the statistic would be given by:
(1)
Replacing the info given we got:
Now we can calculate the p value with this probability:
Since the p value is higher than the significance level provided of 0.1 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean for this case is higher than 31.1MPG using a significance level of 10%. So then the cliam makes sense
X=30
Y≈29.732

Step-by-step explanation:
Given: The dimensions of the wrapping paper :
Now, we know that the area of a rectangle is given by :-
Now, the area of the wrapping paper is given by :-
Step-by-step explanation:
We are given the co-ordinates,
x : -2, -1, 0, 1, 2
y : 8, 5, 2, -1, -4
According to the graph, we see that this function represents a straight line.
The general form of the straight line is y = mx + c, where m is the slope and c is the y-intercept.
So, taking any two points we will find the equation of the straight line.
Consider, (0,2) and (1, -1). Now, slope is given by,
m =
i.e. m = -3
Now, we will find the y-intercept of this equation using (0,2) and m = -3,
i.e. y = -3x + c
i.e. 2 = c
Hence, the equation of the straight line is y = -3x + 2.
