Q1) Using AIU's survey responses from AIU data set, complete following requirements in form of report:
Create two-tailed hypothesis test on either intrinsic or extrinsic variable's data, by using a .05 significance level. Begin by making a null and the alternate statement. Use Microsoft Excel to process your data. Copy and paste the results of output to your report in Microsoft Word. Recognize the significance level, test statistic and critical value. Mention whether you are refusing or failing to reject null hypothesis statement.

ii) Determine the probability which at least 4 vehicles pass this point in next 2 minutes.
iii) Determine expectation of number of vehicles passing through this specified point in ten minutes.
One characteristic of billiard balls is their elasticity - the bounce they get when striking one another. A manufacturer of billiard balls is testing three additives to the basic plastic.
They were planted in four different locations, so we will consider the field as a second factor because different soil and moisture types can also have an effect on yield. The interaction plot below was obtained.
