Answer:
Correct option is (C).
The possible value of the <em>p</em>-value for a one-tailed test are 0.22 and 0.78.
Step-by-step explanation:
The <em>p</em>-value is the probability of acquiring a result as extreme as the observed result, assuming the null hypothesis statement is true.
The <em>p</em> value of a test is:
Left-tailed test:
Right-tailed test:
.
Here,
TS = Test statistic
ts = computed value of the test statistic.
The two-tailed <em>p</em>-value is:
or
.
The <em>p</em>-value of the two tailed test is, 0.44.
Compute the <em>p</em>-value for one-tailed test a follows:


Thus, the possible value of the <em>p</em>-value for a one-tailed test are 0.22 and 0.78.
The correct option is (C).
I believe the answers are C. Acute (all angles less than 90 degrees) and E. Scalene (all 3 sides different values).
Step-by-step explanation:
Principal(P) =$2200
Rate(R) =4%
Time(T)=2 yrs
Simple Interest=PTR/100
I=2200*4*2/100
=$176
10 * (1.025)^9 = 12,48
Maybe 12.49 depending on rounding.
The correct answer is the last choice
