True or false: If P = 0.08, then a. The result is statistically significant at the α = 0.05 level.

Psych stats question #8 show full work

In testing the hypotheses H 0 : p = 0.50 H0:p=0.50 versus H A : p ≠ 0.50 HA:p≠0.50 , a sample of 100 observations produces a test statistic z = 0 z=0 . What is the  p p -value for this test? a1.0000 b 0.6915 c 0.5000 d 0.0000 cNone of the above.

1 - 0.90 = 0.1= 0.1 x 100 = .10 which makes a = .10? is the the correct (one of the correct equations) to find the alpha of a statistic?

When is a variable in a regression statistically significant? 1   When p is more than alpha. 2   When p is more than R2. 3   When p is less than alpha. 4   When p is less than R2. 5   When p is less than the coefficient.

If a treatment is expected to decrease scores in a population with µ= 30, then the alternative hypothesis is µ ≤ 30.  True or false?

If you use α = .001,  using p-value for X1, is the coefficient of X1 is significantly different from 0.  Yes  No

18% of all college students volunteer their time. Is the percentage of college students who are volunteers smaller for students receiving financial aid? Of the 392 randomly selected students who receive financial aid, 55 of them volunteered their time. What can be concluded at the αα = 0.01 level of significance?  H0:  H1: The test statistic ? t z  =  (please show your answer to 3 decimal places.) The p-value =  (Please show your answer to 4 decimal places.) The p-value is ? > ≤  α
