According to the Bureau of Labor Statistics, citizens remain unemployed for an average of 15.9 weeks before finding their next job (June, 2008). Suppose you want to show that Louisiana has been effective in getting their unemployed back to work sooner. You take a random sample of 50 citizens who were unemployed six months earlier and ask them to report the duration. You find that the average time spent unemployed was 13.4 weeks with a sample standard deviation of the time unemployed is 6.7 weeks.

c. -2.11
d. -1.28
e. none of these are correct
Answer:
1
The alternative hypothesis
2
The test statistics
Step-by-step explanation:
From the question we are told that
The population mean value for time citizens remain unemployed is
The sample size is n = 50
The sample standard deviation is 6.7 weeks.
The sample mean value for time citizens remain unemployed is
The null hypothesis is
The alternative hypothesis
Generally test statistics is mathematically represented as

Answer:
Fifty more than half the number of the oranges is one-hundred-and-twenty.
The sum of fifty and half the number of oranges is the same as one-hundred-twenty.
Step-by-step explanation:
The equation is 50 + one-half m = 120.
Assume the number of oranges=m
50+1/2m=120
1/2m=120-50
1/2m=70
m=70÷1/2
=140
All statement that applies includes:
1. Fifty more than half the number of the oranges is one-hundred-and-twenty.
50+1/2m=120
2. The sum of fifty and half the number of oranges is the same as one-hundred-twenty.
50+1/2m=120
Martha can use the two statements above to communicate the correct equation
