Answer:
1. Co-variance= -1.2
2. correlation coefficient= -0.4404
3. There is weak negative relationship between x and y.
Explanation:
1.
Co-variance= Cov(x,y)= sum[(x-xbar)(y-ybar)]/n
xbar=sumx/n=32/5=6.4
ybar=sumy/n=35/5=7
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
Cov(x,y)= sum[(x-xbar)(y-ybar)]/n=-6/5=-1.2
Cov(x,y)=-1.2
2.
correlation coefficient=r
x 7 8 5 3 9
x-xbar 0.6 1.6 -1.4 -3.4 2.6
y 7 5 9 7 7
y-ybar 0 -2 2 0 0
(x-xbar)(y-ybar) 0 -3.2 -2.8 0 0
(x-xbar)² 0.36 2.56 1.96 11.56 6.76
(y-ybar)² 0 4 4 0 0
r=-0.4404
3. Since the value of correlation coefficient is negative and less than 0.5 , so, we can say that there is weak negative relationship between x and y.
After reviewing the arguments and counter-arguments for spending public cash to subsidize stadiums and seasoned sports activities team owners, Coakley concludes that: public money is better on initiatives than constructing a stadium.
The public price range used for a stadium or arena can generate new sales for a metropolis simplest if one of the following conditions happens:
1) the funds generate new spending by using human beings from outside the region who in any other case might not have come to town;
2) the budget motive location citizens to spend money regionally that might not have been.
Maximum of this $7 billion will come from public sources. The subsidy starts offevolved with the federal government, which permits state and nearby governments to difficulty tax-exempt bonds to help finance sports facilities. Tax exemption lowers interest on debt and so reduces the amount that towns and teams ought to pay for a stadium.
Terms on this set (38) most important distinction between publicly and privately funded recreation centers - non-public centers can perform at a loss without an extensive outcry from owners and taxpayers, however, a privately financed facility can perform only for a limited time with poor returns.
