Answer:
b=41
Step-by-step explanation:
180=19v-41+(180-(20v+39))+17v
v=5
180=19v-41+b+17v
180=19(5)-41+b+17(5)
b=41

Answer:
Step-by-step explanation:
Given that Home sales has 95% confidence interval to estimate the average loss in home value.
a) If std deviation of losses doubles as 3000 from 1500, we have margin of error also increases. Because margin of error
= ±Critical value * Std error
= ±Critical value * Std dev/sqrt n
Hence we find that whenever std deviation increases the margin of error increases, for the same level of confidence.
b) Whenever confidence level increases, critical value increases and as a result margin of error increases. Hence by reducing from 95% to 90% confidence interval would be reduced. True
c) Instead of changing conf level, increasing sample size would give more reliale and accurate results.
We know that
<span>A pitcher of water contains 1/4 liters of water--------------> 0.25 lt
then
0.25 lt/5--------> 0.05 lt
In each glass are 0.05 lt of water
1 lt-------------> 1000 ml
0.05 lt----------> X
X=0.05*1000--------> X=50 ml
the answer is
</span>In each glass are 0.05 lt of water
In each glass are 50 ml of water<span>
</span>
