[answerhappygod]

the relationship between age(X ,in year) and the number ofoverseas holidays year (Y) has been studied using simple linearregression sing following model
=++
the following table shows the data of age and the numberof overseas destinations for a random sample of 20 respondents
Age(X) 62 57 40 49 67 54 43 65 54 41
no of overseas holiday(Y) 6 5 4 3 5 5 2 6 3 1
Age(X) 44 48 55 60 59 63 69 40 38 52
no of overseas holiday(Y) 3 2 4 5 4 5 4 2 1 3
the summary of the data is as follows where SST is the total sumof squares SSR is the regression sum of squares
Xi=1060,=73 , =57994,=311,=4097,
SST=(-)2 =44.55,SSR= (ÿi- ))2=28.65
a)find the estimated regression line I = Bo+b1Xi that links the agewith the number of overseas holidays in a year .
b)test whether coefficient b1 is statistically significant or not use 5% significant level.
c)interpret the estimated slope coefficient, b1.
d) suppose that Ah Huat is 50 years old ,predict how many times he has gone overseas for a holidays?
e) give one quantitative and one qualitative variable that areexpected to affect the number of overseas holiday in a year.
