Answer:
900 sample size
Step-by-step explanation:
To determine the sample size for a proportion, the margin of error formula is used to determine this:
Where p is the proportion, E is the margin of error, n is the sample size, q = 1 - p, is the z score.
Since the proportion is not known, the sample size needed to guarantee the confidence interval and error is at p = 0.5 and q = 1 - p = 1 - 0.5 = 0.5
E = 5% = 0.05, = 3. Hence:
Answer:
and growth rate factor is 0.075
Step-by-step explanation:
The function that models the population of iguanas in a reptile garden is given by , where x is the number of years.
Since,
i.e. .
Therefore, the monthly growth rate function becomes,
i.e. .
i.e. .
Hence, the monthly growth rate is i.e. .
Also, the growth factor is given by = 0.075.
Thus, the growth factor to nearest thousandth place is 0.075.
