In: Statistics and Probability
I get confused when it gives me a list of data instead of numbers to input...lol. HELP!
You wish to test the following claim ( H a ) at a significance level of α = 0.05 .
H o : μ = 65.8
H a : μ < 65.8
You believe the population is normally distributed, but you do not know the standard deviation.
Data 77.9 49.7 49.0 64.7 51.9 48.2 51.4 58.6 53.7 63.2 68.0 54.1 70.1 55.9 70.7 61.7 54.9 64.2 57.5 56.2 63.7 75.5 68.9 46.3 52.9 79.6 59.7 76.6 70.7 75.5 65.2 62.2 69.5 67.8 65.2 69.2 63.2 59.9 59.4 66.5 53.3 61.0 70.7 62.7 53.3
What is the test statistic for this sample? test statistic = Round to 3 decimal places
What is the p-value for this sample? p-value = Use Technology Round to 4 decimal places.
The p-value is... less than (or equal to) α, greater than α
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 65.8.
There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 65.8.
The sample data support the claim that the population mean is less than 65.8.
There is not sufficient sample evidence to support the claim that the population mean is less than 65.8.
