Population was 12.621 when it was measured
Next year it rose by 6%, so add that 6% to 100% and multiply with population measured
12.621 × (100%+6%) = 12.621 × 106% = 13.379,24
Since a man cant be 0,24, we count that as +1
13.379,24 = 13.379 + 1 = 13.380
That was for a year after measurement, now let's calculate for another year
Now, add those 6% to a new population number
13.380 × (100%+6%) = 13.380 × 106% = 14.182,8
since 0,8 isn't a man, instead we add again +1
14.182,8 = 14.182 + 1 = 14.183
now let's do it for another year after last, by adding those 6% to a newest population number
14.183 × (100%+6%) = 14.183 × 106% = 15.033,98
round it again to +1, since 0.98 isn't a man
15.033,98 = 15.033 + 1 = 15.034
that is it, now graph is in the picture.

Answer:
a) On average, homes that are on busy streets are worth $3600 less than homes that are not on busy streets.
Step-by-step explanation:
For the same home (x1 is the same), x2 = 1 if it is on a busy street and x2 = 0 if it is not on a busy street. If x2 = 1, the value of 't' decreases by 3.6 when compared to the value of 't' for x2=0. Since 't' is given in thousands of dollars, when a home is on a busy street, its value decreases by 3.6 thousand dollars.
Therefore, the answer is a) On average, homes that are on busy streets are worth $3600 less than homes that are not on busy streets.
Answer:
Step-by-step explanation:
Given that 33.4% of people have sleepwalked.
Sample size n =1459
Sample favourable persons = 526
Sample proportion p =
Sample proportion p is normal for large samples with mean = 0.334 and
std error =
a) P(526 or more of the 1459 adults have sleepwalked.)
b) Yes, because hardly 1.4% is the probability
c) 33.4 is very less compared to the average. Either sample should be improved representing the population or population mean should be increased accordingly.
