Answer:
(1) 68.811 L
Step-by-step explanation:
The amount being subtracted is ...
16 + 0.18 + 0.009 = 16.189 . . . . liters
The difference is ...
85.000 -16.189 = 68.111 . . . liters

<em>Additional comment</em>
cL is the SI unit "centiliters." The prefix "centi-" mean 1/100 or 0.01 units. Then 18 cL = 18 × 0.01 L = 0.18 L.
mL is the SI unit "milliliters." The prefix "milli-" means 1/1000 or 0.001 units. Then 9 mL = 9 × 0.001 L = 0.009 L.
Answer:
z(s) is in the rejection region. We reject H₀. We dont have enought evidence to support that the cream has effect over the recovery time
Step-by-step explanation:
Sample information:
Size n = 100
mean x = 28,5
Population information
μ₀ = 30
Standard deviation σ = 8
Test Hypothesis
Null Hypothesis H₀ x = μ₀
Alternative Hypothesis Hₐ x < μ₀
We assume CI = 95 % then α = 5 % α = 0,05
As the alternative hypothesis suggest we should develop a one tail-test on the left ( we need to find out if the cream have any effect on the rash), effects on the rash could be measured as days of recovery
A z(c) for 0,05 from z-table is: z(c) = - 1,64
z(s) = ( x - μ₀ ) / σ/√n
z(s) = ( 28,5 - 30 ) / 8/√100
z(s) = - 1,5 * 10 / 8
z(s) = - 1,875
Comparing z(s) and z(c)
|z(s)| < |z(c)| 1,875 > 1,64
z(s) is in the rejection region. We reject H₀. We dont have enought evidence to support that the cream has effect over the recovery time
Answer:
To find the median you cross off the first few numbers and the last few until you get to the middle then when you get the middle number that will be your median
Step-by-step explanation:
Answer:
Female=14 male=6
Step-by-step explanation:
Oof this toke long I understand it now, for yesterday you gotta do 6+6+6+6+6=30 this is the male and so you add 14 to 30=44, now comes the important part of solving this problem. For today you gotta add 4 men and 4 women so you do 6+6+6+6=24 now 14+14+14+14=56 and if you add 56+24=80 .
