Suppose Wall Street securities firms paid out year-end bonuses of $125,500 per employee last year. We take a sample of employees at the ASBE securities firm to see whether the mean year-end bonus is less thanthe reported mean of $125,500 for the population. You wish to test the following claim (Ha) at a significance level of =0.002. Ho:=125500 Ha:<125500
You believe the population is normally distributed and you know the standard deviation is =2400. You obtain a sample mean of x=124815.3 for a sample of size n=65.
What is the test statistic for this sample? test statistic = (Report answer accurate to 3 decimal places.) What is the p-value for this sample? p-value = (Report answer accurate to 4 decimal places.) The p-value is...
- less than (or equal to)
- greater than
This test statistic leads to a decision to...
- reject the null
- accept the null
- fail to reject the null
the final conclusion is that...
- There is sufficient evidence to warrant rejection of the claim that the population mean is less than 125500.
- There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 125500.
- The sample data support the claim that the population mean is less than 125500.
- There is not sufficient sample evidence to support the claim that the population mean is less than 125500.
