How do I tell if a T-test is significant with an alpha of 05 and if you already have significance values?
If you already have your p-value, compare it with 0.05. If the p-value is less than an alpha of 0.05, the t-test is significant. If it is above 0.05, the t-test is not significant.
Reject Ho or do not reject H0?
Rejecting or Failing to reject the Null Hypothesis (Ho) depends of the P-Value. Generally, the P-value (probability( Observation | Ho ) ) is around .05, thus minimizing the Type 1 error rate. If the P-value < Alpha , you would reject the Ho, and instead believe the Ha (Alternative Hypothesis), and if the P-value > Alpha, you would Fail to reject the Ho because there is not enough evidence to believe the Ha.
Can you not reject null hypothesis?
you do not need to reject a null hypothesis. If you don not that means "we retain the null hypothesis." we retain the null hypothesis when the p-value is large but you have to compare the p-values with alpha levels of .01,.1, and .05 (most common alpha levels). If p-value is above alpha levels then we fail to reject the null hypothesis. retaining the null hypothesis means that we have evidence that something is going to occur (depending on the question)
Can p value equal 1?
Yes, if p=1 that means an event is 100% certain to happen. For example, p value for picking a day of the week in the Enlish Language that ends in AY is 1 or 100%.P values can be anywhere between 0 and 1 inclusive. For for an event, E, we can always say 0< or equal to P(E)< or equal to 1.
What is the value of 12P3?
It is 12*P*P*P whose value will depend on the value of P.
What does 5 times p equal?
That depends on the value of "p".

What happens when probability value is greater than alpha value?
When probability value (p-value) is greater than alpha value, we fail to reject the null hypothesis.Probablity value is the probability of obtaining an answer equal to or more extreme than the observed value.Alpha value is the level of significance. It's the value set that determines if a result is statistically significant, or in other words, if it's not likely to have occurred simply due to chance. Alpha value is usually 5%.There are two hypotheses when we conduct a hypothesis test: the null hypothesis and the alternative hypothesis.The null hypothesis acts as a default position. It's usually an assumption that there is no relationship between two events or that a treatment has no effect. In most legal systems, the null hypothesis would be that the defendant is innocent.The alternative hypothesis is what we would assume if we reject the null hypothesis. We reject the null hypothesis when the probability value is less than the alpha value.

What does z equal for an a equals 0.01 and a lower level test?
For a lower level test with significance level (alpha) 0.01, the z value is -2.33. That is, P( z < -2.33) = 0.01. The area to the left of -2.33 is 0.01.

How many P's are equal in value to 0 pound and 8 p?
eight £0.08 = 8 pence
What has the author Alpha P Jamison written?
Alpha P. Jamison has written: 'Elements of mechanical drawing ...'

What is 5 greater than or equal to p minus 3?
It is an inequality than can be solved for p: 5 ≥ p - 3 → p - 3 ≤ 5 → p ≤ 8 So any value less than, or equal to, 8 will do for p.
What type of operator can be used to determine whether a specific relationship that exists between two values?
The relational operators: ==, !=, =.p == q; // evaluates true if the value of p and q are equal, false otherwise.p != q; // evaluates true of the value of p and q are not equal, false otherwise.p < q; // evaluates true if the value of p is less than q, false otherwise.p q; // evaluates true if the value of p is greater than q, false otherwise.p >= q; // evaluates true of the value of p is greater than or equal to q, false otherwiseNote that all of these expressions can be expressed logically in terms of the less than operator alone:p == q is the same as NOT (p < q) AND NOT (q < p)p != q is the same as (p < q) OR (q < p)p < q is the same as p < q (obviously)p q is the same as (q < p)p >= q is the same as NOT (p < q)
Find a p-value given z and the population mean Find the P-value in a test of the claim that a population mean is equal to 100 given that the test statistic is z equals 1.50?
The probability of observing a z value equal to or more extreme than 1.50 is 0.1336
