For this case we have a function of the form:
Where,
n0: initial amount (in units of millions)
b: growth rate
t: time in years
Substituting values we have:
Answer:
the number of toys being produced, n (in millions), in t years is:

Answer:
The null and alternative hypotheses are:
Under the null hypothesis, the test statistic is:
Where:
is the sample mean
is the sample standard deviation
is the sample size
Now, the right tailed t critical value at 0.05 significance level for df = n-1 = 10-1 = 9 is:
Since the t statistic is less than the t critical value at 0.05 significance level, therefore,we fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim that the average phone bill has increased.
