Using formula:




Calculating the value of standard error:


Calculating the value of test statistic:
Formula:


Calculating the value of Degree of freedom:

Because the P-value is a 2-tailed test = 0.0018
Thus they reject H0, because of P-value < 0.05,
Yeah, certain data show clearly that the means are different.
Answer:
0
Step-by-step explanation:
The slope is the variation of the inclination of a straight line.
It's measured by calculating the variation of the y values (rise) over the variation of the x values (run). Let's take 2 points over that line: (0,-3) and (2,-3).
We see the variation of y values is 0: -3 - -3 = 0
The variation of x values is 2: 2 - 0 = 2
So, the slope is 0/2, so 0.
Horizontal lines don't have a slope because they don't vary in the y values... just like a flat land isn't a hill, there's no slope.
Step-by-step explanation:
0.000
ones, tenths, hundreths, thousandths
Refer to above when you get confused in the future! You got this! :)
2.
2a) 0.482
2b)0.18
2c)8.001
2d)0.008
2e)0.018
3. 58/100 = 0.58
Subtract the sum of the three test scores from the product of 75 and 5 and then divide the result by 2
hope this helps xoxo
