Question 881136: Here are our Hypothesis:
Ho: population mean μo = 200
Ha: population mean μo < 200
This will be Left-Tailed test.
Population Standard Deviation σ = 50
Significance level is 0.10 (10%).
Critical z-value for 10% significance level is 1.28.
For sample mean x and sample size n use
numbers assigned sample mean x is = 180 and sample size n= 16
1. Calculate your test statistics z-value: z = (x - 200)/(50/√n)
2. Does your sample statistics z value falls in rejection region to the left of -1.28?
3. Will you reject or do not reject Ho?

Question 617860: 2145000 + x/858000 + x = 2
2=(2,145,000+X)/(858,000+X)
Cross multiply to get:
2(858,000 + X) = 2,145,000 + X
1,716,000 + 2X = 2,145,000 + X
Subtract X from both sides
2X- X = 2,145,000 � 1,716,000
Subtract 1,716,000 from both sides
X = 429,000
