Step-by-step explanation:
Answer: The answer is 58. Hope this helps!
Y doesn't change so it stays 3.
x will be 0, because the average of 0 and -2 is -1
Answer:
2.897
Step-by-step explanation:
Let us find the mean and variance for the sample first.
105 104 110 112
114 106 108 109
Mean = sum/8 = 108.5
Variance = 12
Std dev = sq rt of variance = 3.464
Std error = std dev/ sq rt n
since n =8, we get std error = 1.225
Since sample size is small, df =8-1 =7
For 95% confidence intervals, t critical value for two tailed=2.365
Margin of error = std error x t critical = 1.225(2.365)
=2.897
Yes it x2 is a factor because at some point and time 2x would cross 4x
