question 53

Multiple Choice

The heights (in cm) for a random sample of 60 males were measured.The sample mean is 166.55,the standard deviation is 12.57,the sample kurtosis is 0.12,and the sample skewness is −0.23.The following table shows the heights subdivided into non-overlapping intervals. For the goodness-of-fit test for normality,the null and alternative hypothesis are ______________________________________________________________________.

• A) H₀: Heights follow a normal distribution with mean 166.55 and standard deviation 12.46,H_A: Heights do not follow a normal distribution with mean 166.55 and standard deviation 12.46
• B) H₀: Heights do not follow a normal distribution with mean 166.55 and standard deviation 12.46,H_A: Heights follow a normal distribution with mean 166.55 and standard deviation 12.46
• C) H₀: Heights follow a normal distribution with mean 166.55 and standard deviation 12.57,H_A: Heights do not follow a normal distribution with mean 166.55 and standard deviation 12.57
• D) H₀: Heights do not follow a normal distribution with mean 166.55 and standard deviation 12.57,H_A: Heights follow a normal distribution with mean 166.55 and standard deviation 12.57
