Test Statistics: Population Mean (Z vs t)Version en ligne

par melody arais

If the population SD is known and n is large, the test statistic for a single mean is a:

A sample mean is 105, population mean 100, SD known 15, n=36. The z value is:

When SD is unknown and sample size is small, you should use a:

Which statement describes a critical value?

For a 95% two-tailed test with unknown SD, the critical t-value depends on:

If t-statistic > t_crit (df=20, alpha=.05), we:

The null hypothesis for testing a single mean is usually:

With known SD and small n, the correct approach is:

In a z-test, the test statistic is calculated as:

Critical value for a one-sided z-test at alpha=0.05 is:

Given : sample mean = 310 ; population mean = 307 ; s = 40 ; sample size n= 26

what is the value of the test statistic in number 11?

Given : sample mean = 67.5 ; population mean = 62.5; standard deviation = 8 ; n = 50 , what test statistic must be used?

given: Ho = 120 ; Ha # 120 ; z computed = 2.33; z-critical value = 1.96. What conclusion can be drawn from the given information?

Given : Ho = 205 ; Ha > 205 ; Z computed = 2.000 ; Z critical value = 2.015. What conclusion can be drawn from the given information?
