You wish to test the following claim (HaHa) at a significance level of=0.05=0.05. Ho:=86.1Ho:=86.1 Ha:<86.1Ha:<86.1 You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data:

data

58.2

75.8

55.6

44.1

56.1

72.5

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 86.1.
• There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 86.1.
• The sample data support the claim that the population mean is less than 86.1.
• There is not sufficient sample evidence to support the claim that the population mean is less than 86.1.
