Question 24 3 pts Suppose that the underlying population is normally distributed. From a random sample of 16 individuals from this population, the sample mean is 8 and the sample standard deviation is 10. Suppose someone claims that the true population mean is 3. The value of the t-test statistic is and the null hypothesis be rejected at the 10-percent level of significance. 1.2; cannot 2; can 3.2; cannot O 1.8; can

O True O False Question 7 3 pts In order to calculate the p-value of a test statistic we need to know the level of alpha for our test.

In comparing two population means, an unpaired test provides more precise results than a paired test because the unpaired test uses two independent samples while the paired test uses a single sample. True O False Question 2 1 pts When comparing two population means, if the variations which are unique to each population are very small compared to the variations which are common to both populations, it is reasonable to assume that the population standard deviations are not equal. O...

Question 1 5 pts We're interested in whether Biology students have higher Visual relative to Kinesthetic learning styles. We've decided to use a paired t-test to investigate the question, based on our classroom as our sample. What assumptions do we have to make to use this method? our sample is an unbiased representative sample of the population both the Visual...

To test Ho: = 50 versus H=50, a simple random sample of size n = 40 is obtained. Complete parts (a) through below Click the icon to view the table of critical t-values (a) Does the population have to be normally distributed to test this hypothesis by using t-distribution methods? Why? O A. No-there are no constraints in order to perform a hypothesis test. O B. No-since the sample size is at least 30, the underlying population does not need...
