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.

Here is the instruction and code: LewList *splitStrange(); This function should split the list in two, adding the...

-- I can calculate the formula mass but get confused with the various conversions between different types of units. I have the correct answers but I am trying to learn how to work through the problems to get the correct answer. 10) A sample of talc, Mg3Si4O10(OH)2, has a mass of 0.664 g. Calculate the number of mmoles of Mg3Si4O10(OH)2. 11) A sample of gypsum, CaSO4•2H2O, has a mass of 22 g. Calculate the number of moles of CaSO4•2H2O. 12)...

With my promotion came not only a raise, but more responsibilities and new tasks that I never thought I'd be capable of doing. Becoming an administrative manager from being a server was a big change for me. I was comfortable with being able to clock in and out only having to deal with customers. Now, I don't only deal with customers, I...
