Answer:
2)8%
3)=
$
26.46
4)multiply $1.50 and 60%, which will give you 0.9. now multiply $1.50 and 0.9 and that'll give you$1.35. lastly, add $1.50 and $1.35 and that'll give you the answer which is $2.85.
5)15 % of $1580 is $237
6)25%

Answer:
Linear correlation exists
Step-by-step explanation:
Given the data :
X : | 2 4 5 6
Y : | 6 9 8 10
Using technology to fit the data and obtain the correlation Coefficient of the regression model,
The Correlation Coefficient, r is 0.886
To test if there exists a linear correlation :
Test statistic :
T = r / √(1 - r²) / (n - 2)
n = number of observations
T = 0.886 / √(1 - 0.886²) / (4 - 2)
T = 0.866 / 0.3535845
T = 2.449
Comparing Pvalue with α
If Pvalue < α ; Reject H0
Pvalue = 0.1143
α = 0.05
Pvalue > α ; We reject the null and conclude that linear correlation exists
