Answer:
Both means are apprxoimately equal at 1% level of significance.
Step-by-step explanation:
Given is the information summarised below
Group Men Women
Mean 23.00 28.00
SD 5.00 10.00
SEM 1.00 1.83
N 25 30
H0: Mean of mean = mean of women
Ha: means of men < mean of women
(Left tailed test)
Since population std deviation is known but sample sizes are small t test is used.
The mean of Men minus Women equals -5.00
standard error of difference = 2.201
t = 2.2721
df = 53
p value= 0.0136
since p >0.01 at 1% significance level we fail to reject H0.
Both means are apprxoimately equal at 1% level of significance.
Answer:
51 meters
Step-by-step explanation:
The shape of the backyard is rectangular having a length, l=45 meters, and a width, w=24 meters as shown in the figure.
As wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. So,
The length of fencing = The length of the diagonal AC or BD
As the length of both the diagonals of a rectangle are equals, AC=BD.
The length of fencing
[length of the diagonal]
meters
Hence, Steve needs 51 meters of fencing.
Yes becuase the x value is always the independent variable while R is dependent of that variable
therefore if 1 is the x and the graph is linear (a straight line) than it would be the unit rate of the situation/graph
