Answer:
$5903.39
Step-by-step explanation:
This can be solve using compound interest formula. The formula is:
Where
F is the future amount (what we are looking for)
P is the present amount (which is 4800)
r is the rate of compound interest per year, in decimal (3% per year, 3/100 = 0.03)
t is the time in years ( t = 7)
Now we substitute these values into the formula and find F:
So, Colin would have $5903.39 after 7 years, in his account.
Answer:
We fail to reject the null hypothesis and accept it.
Step-by-step explanation:
We are given the following in the question:
Hypothesis:
Mean number of recorded participants
Calculated test statistic = 13.86
Critical value = -1.751
We are conducting a left tailed hypothesis.
Rejection region:
If the calculate test statistic is less than the critical value, we fail to accept the null hypothesis and reject it.
We accept the alternate hypothesis.
Since,
We fail to reject the null hypothesis and accept it. Thus, the test result are not statistically significant and and at best provide weak evidence against the null hypothesis.
