Luis earns a solid $150 and that doesn't change, now you need to calculate 14% of $6,050.
x=150+(0.14x6050)
150+(847)
997
Luis was paid $997.
Answer:
<h2>0.15 inches per month</h2>
Step-by-step explanation:
step one:
This problem is focused on the growth rate of a plant.
given data
the plants grow 5 inches in 34 months
and also that 1 month= 4 weeks
step two:
We can still say that
if 34 months see a growth of 5 inches
then 1 months will be X inches
cross multiply we have
X= 5/32 inches
step three:
converting this number to decimal we have
X= 0.15 inches per month
Therefore the growth rate would be
0.15 inches per month
Since in this case we are
only using the variance of the sample and not the variance of the real population,
therefore we use the t statistic. The formula for the confidence interval is:
<span>CI = X ± t * s / sqrt(n) ---> 1</span>
Where,
X = the sample mean = 84
t = the t score which is
obtained in the standard distribution tables at 95% confidence level
s = sample variance = 12.25
n = number of samples = 49
From the table at 95%
confidence interval and degrees of freedom of 48 (DOF = n -1), the value of t
is around:
t = 1.68
Therefore substituting the
given values to equation 1:
CI = 84 ± 1.68 * 12.25 /
sqrt(49)
CI = 84 ± 2.94
CI = 81.06, 86.94
<span>Therefore at 95% confidence
level, the scores is from 81 to 87.</span>
