This would be a positive answer because 400/2 = 200 which is a positive number/integer
Answer:
b) use a two-sided test instead of a one sided test.
Step-by-step explanation:
If we are using a significance level of 0.05, then the two-tailed test assigns half alpha to test for statistical significance in one direction and half alpha to test statistical significance in the other direction. This implies that .025 is present in each tail of the test statistical distribution. When using the two-tailed test, regardless of the direction of the relationship you assume, we test the possibility of the relationship in both directions.
Answer:
Mean: 35
Median: 31
Mode: 36.9 (If you round up), 36.8 (If you don't round up)
Step-by-step explanation:
Order the Data: 29, 30, 30, 31, 31, 35, 35, 35, 36
Mean: Average , sum all of your data and divided by how many scores are in your data. (From Math Notes I have)
332/9 = 36.9 (If you round up)
Median: Middle Score (From Math Notes I have)
In this case the Median is 31.
Mode: The score that up most (From Math Notes I have)
In this case the Mode is 35.
Answer:
( -3.5, 1.5 )
Step-by-step explanation:
You have to use slope-intercept form to solve this; y=mx+b
m= 7/2 (x,y) = (-3,3)
3 = 7/2 (-3) + b
3 = 10.5 + b
b = -7.5
y = 7/2 - 7.5
The coordinates would be ( -3.5, 1.5 )
The ERROR Josephina and Dario estimated √50 are such as 0.07 and -17.92.
<h3>How to calculate the error?</h3>
Suppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
WE need to find the error Josephina and Dario are estimating √50
The actual value of
So,
By Josephina
Error = Actual value - Estimated value
Error = 7.07 - 7
Error = 0.07
By Dario
Error = Actual value - Estimated value
Error = 7.07 - 25
Error = -17.92
Hence, the ERROR Josephina and Dario estimated √50 are such as 0.07 and -17.92.
