Answer:
The value of the slope c is -6,487.168
Step-by-step explanation:
In this question, we are told to find the y-intercept of a regression line model.
Mathematically, a regression model having a single dependent variable y and a single independent variable x can be represented by the equation of a straight line.
This is the same as;
y = mx + c
where m is the slope and c is the y intercept
Now from the question, we know we are to calculate c , where y is the mean of the y-coordinates at a value of 12.312, where x is also the mean of the x-coordinates at a value of 3448 and an m-value which is the slope at 1.885
We plug these values into the straight line equation to yield;
12.312 = 1.885(3448) + c
c = 12.312 - 1.885(3448)
c = 12.312 - 6,499.48
c = -6,487.168
Answer:
$200 is not part of the confidence interval, which means that this is not a reasonable conclusion, at the 100 - 95 = 5% level of significance.
Step-by-step explanation:
95% confidence interval: $72 to $198.
This means that we are 95% sure that the true mean spending is between $72 and $198.
From this confidence interval the assistant concluded that people spend an average of $200 a month on entertainment. Is this a reasonable conclusion and why?
$200 is not part of the confidence interval, which means that this is not a reasonable conclusion, at the 100 - 95 = 5% level of significance.
Answer:
7.50h+0.75s 63.75 30
Step-by-step explanation:
7.50 x how many hours + 0.75 x how many sunglasses he sold
7.50 x 6 + 0.75 x 25= 63.75
7.50x8= 60 0.75x40=30 60+30=90
1) one is multiple of all positive integers. So, yes it is multiple of all that numbers.
2) Two is multiple for all those number which has even digit in unit place. So, yes they all are multiple of 2 too.
