mixed number form: 434 6/23
Step-by-step explanation:
Answer:
Step-by-step explanation:
Using either the critical value rule or the p-value rule, a conclusion can be drawn at a level of significance (alpha)
The null hypothesis: u = hypothesized mean
Alternative hypothesis: u > u0 or u < u0 for a one tailed test
Alternative hypothesis for a two tailed test: u =/ u0
To draw a conclusion by failing to reject the null hypothesis as stated then: using critical value
Observed z score > critical z score for both the one and two tailed test.
Or using p value:
P-value > alpha for a one tailed test
P-value > alpha/2 for a two tailed test
Thus, if a one-sided null hypothesis for a single mean cannot be rejected at a given significance level, then the corresponding two-sided null hypothesis will also not be rejected at the same significance level.
Answer:
13 sides
Step-by-step explanation:
1980 = (n − 2)×180 Formula for number of sides
n − 2 = 1980/180 Divide both sides by 180
n - 2 = 11
+ 2 + 2 Add 2 to both sides
n = 13
The commutative property of addition states that the order of addition doesn't affect the solution. Thus, 4.8 + 5.2, by the commutative property of addition, is the same as 5.2 + 4.8
