Question
Use technology to help you test the claim about the population mean, H, at the given level of significance, a, using the given sample statistics. Assume the population is normally distributed. Claim: > 1160: : 0.02; : 198.26. Sample statistics: x= 1182.06, n: 250 ldentify the null and alternative hypotheses. Choose the correct answer below. A. B. Ho: Hs 1160 Ha : > 1160 HOP> 1182.06 Ha : s1 182.06 Ha : 1160 Ha: u 1182 06 on Ho: 1182.06 Ha : > 1 182.06 ) C. Ho.> 1160 E. Ho: H2 1182.06 F. Ho H 2 1160 Ha :Explanation / Answer
The statistical software output for this problem is:
One sample Z summary hypothesis test:
: Mean of population
H0 : = 1160
HA : > 1160
Standard deviation = 198.26
Hypothesis test results:
Hence,
Standardized test statistic = 1.76
Mean n Sample Mean Std. Err. Z-Stat P-value 250 1182.06 12.539063 1.7593021 0.0393Related Questions
