Answer:

y = 50·3^x
(2, 450), (3, 1350), (4, 4050), (5, 12150)

Step-by-step explanation:

The problem statement tells you each observed count is 3 times the last one.

Expressed as an exponential function with an initial value of 50 and a growth factor of 3, the formula is ...

Answer:

[34,54]

Step-by-step explanation:

-The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.

Where:

68% is the first standard deviation
95% is the second standard deviation about the mean
99.7% is the 3rd standard deviation about the mean.

-Therefore. the middle 95% interval is calculated as:

$CI=\mu+2\sigma\\\\=44\pm 2(5)\\\\=44\pm 10\\\\=[34,54]$

Hence, the interval is [34,54]
