Answer:
=5803.28$ and 1760.99 $
Step-by-step explanation:
Given that Emile Zola, a senior Manager for Timber eye industries in California got a merit raise of 7.25% and cost of living 2.2%
Total increase in percent =
After rise Emile salary is 87609.50 $
Let Emile salary -- 100
RIse -- 9.45
Salary after rise -- 109.45
THus we get if 109.45 is raised salary then merit increase =7.25
Hence for 87609.50, merit increase = =5803.28$
Similarly we have cost of living increase=
=
Answer: 0.283
Step-by-step explanation:
Formula to find the lower limit of the confidence interval for population proportion is given by :-
, where = sample proportion.
z* = Critical value
n= Sample size.
Let p be the true proportion of people who would purchase a defective item.
Given : Sample size = 993
Number of individuals would buy a slightly defective item if it cost less than a dollar = 305
Then, sample proportion of people who would purchase a defective item:
Critical value for 90% confidence interval = z*=1.645 (By z-table)
The lower bound of a 90% confidence interval for the true proportion of people who would purchase a defective item will become
[rounded to the nearest three decimal places.]
Hence, the lower bound of a 90% confidence interval for the true proportion of people who would purchase a defective item.= 0.283
