Just simply divide
4 divided by 5= .8
So 8 tenths are equal to 4/5
In this question, we need to find this year's tuition.
We know that last year's tuition was 29,613 dollars.
We know that this year's tuition increased by 5.9%
In order to find your answer, we would have to multiply 29,613 by (1 + 0.059 = 1.059), since the price is increasing.
Solve:
29,613 · (1 + 0.059 = 1.059)
29,613 · 1.059 = 31,360.167
If you have to round to the nearest hundredths, it would be: 31,360.17
If you have to round to the nearest whole, it would be: 31,360
This means that this year's tuition was $31,360
Answer:
$31,360 (if you need to round to the nearest whole)
$31,360.17 (if you need to round to the nearest hundredths)
Answer:
1. y = 0.437798+0.829539X
2. there is a significant effect
3. 7.523
4. 41.914
5. no
6. 0.8777
Step-by-step explanation:
1.
from the regression output we have
intercept = 0.437798
slope = 0.829539
the regression line would therefore be =
y = 0.437798 + 0.829539X
2.
h0 = regression is not significant
h1: regression is significant
alpha = 0.05
p value = 0.0001
we compare p-value with alpha
0.0001<0.05
we therefore reject H0 and conclude that hours spent studying have significant effect on total points.
3.
To get standard error of estimate:
mean sum of squared error = MSE
MSE = 56.5974
= √56.5974
= 7.523
4.
points of a student who spent 50 hours studying. we calculate this from the regression line
y = 0.437798 + 0.829539X
x = 50
y = 0.437798 + 0.829539(50)
y = 41.914
5.
no I would not be comfortable using estimate regression equation to predict his point of a student spent 120 hours studying. this value is out of range of the predictor values (independent variables)
6. to get r² (r squared)
r² = SSR/SST
SSR = 3249.72
SST = 3702.5
r² = 3249.72/3702.5
= 0.8777
7.
we are supposed to solve question 7 from question 8. but no question 8 was given. hence no solution
