Answer:
y=-.386x + 2.879
Explanation:
For these type of calculations, you would have to use a graphing calculator to use the <em>linear regression</em> function. What this does is, it takes the x & y values given on the chart and it gives you the best possible linear equation for the given data set.
The exact results were:
y = -0.3862928349 + 2.869158879
Answer:
Step-by-step explanation:
a) 
b) Sample mean is the average of sample
c) std deviation of the sample
d) std dev/sq rt n
e) (sample mean - mu)/std error
f) p value = prob with test statistic
g) If p < alpha, reject H0.
h) If rejected, there is evidence that significant difference between population mean and sample mean.
It is neither a direct variation or a inverse variation
