You wish to test the following claim (HaHa) at a significance level of=0.10 Ho:=72. Ha:<72. You believe the population is normally distributed andyou know the standard deviationis=12.6=12.6. You obtain a sample mean ofM=71 for a sample of sizen=56 What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = 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 As such, the final conclusion is that...
• There is sufficient evidence to warrant rejection of the claim that the population mean is less than 72.3.
• There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 72.3.
• The sample data support the claim that the population mean is less than 72.3.
• There is not sufficient sample evidence to support the claim that the population mean is less than 72.3.
