Question

A substance used in biological and medical research is shipped by airfreight to users in cartons of 1,000 ampules. The substance is expensive and therefore expensive to insure for purposes of alrfreight delivery. The airfreight company is especially interested in minimizing airfreight breakage of this and other similar products. Data were collected involving 16 shipments on the number of times the carton was transferred from one aircraft to another over the shipment route and the number of ampules found to be broken upon arrival. One of the company's analysts fits a regression model to explain breakage from the number of transfers. The diagnostic information below was obtained. Use this information to answer the following questions. Use a 5% level of significance. AD 0.193 P-Value 0.875 (a) What is being tested here? (Choose one) o Whether all of the x variables are important in predicting y. The assumption of normally-distributed disturbances. o The assumption of independence. O The assumption of constant variance. o The assumption of linearity. O whether there is alinear relationship between x and y, (b) which hypotheses are being tested? (Choose one) o Ho: All of the x variables in the model are not important H.: Atleast one of the x variables is important o Ha: 1.0 H.: 1.0 o Hs: The model variance is oonstant H.: The model variance is not constant Hai Disturbances are non-norm MacBook Pro

Explanation / Answer

Answer:

a). The assumption of normally distributed disturbances.

b).

H0: Disturbances are normal

Ha: Disturbances are non normal

c).

Reject Ho if p < 0.05

Do not reject Ho if P 0.05

d). Anderson -Darling

e).

test statistic =0.193

P=0.875

f).

Do not reject Ho. The assumption of normally distributed disturbances has been met.
