Answer:
Confidence interval = ( 0.7991, 0.8647 )
Step-by-step explanation:
Sample size = n = 351
number of successes = X = 292
Sample proportion = P = 
= 
= 0.831908831
confidence interval = 90%
Critical Z value = 1.6449 [by using excel]
Confidence interval = P ± Z 
Where P = Sample proportion
Z = critical value
n = sample size
Confidence interval = 0.831908831 ± 1.6449 
= 0.831908831 ± 1.6449 × 0.0200
= 0.831908831 ± 0.032898
Lower limit = 0.831908831 - 0.032898 = 0.7991
Upper limit = 0.831908831 + 0.032898 = 0.8647
Confidence interval = ( 0.7991, 0.8647 )
Answer:
$45
Step-by-step explanation:
For calculating the magnitude of quantities we use the absolute value. The absolute |x| of a number x is value of x regardless to its sign. So we will have |x| = x if x is positive, and |x| = −x if x is negative, which means that our result will be always positive.
This means that the magnitude of the amount overdrawn is |-$45|=$45

Answer:
about 145.3 mg
Step-by-step explanation:
If half breaks down in the hour, then half remains. That is, each hour the amount remaining is multiplied by 1/2. The remainder after 6 hours is ...
(9300 mg)(1/2)^6 = 145.3125 gm
About 145.3 mg will be left after 6 hours.
The solution would be x=0 because the statement is false.
