First ln on both sides to bring down the powers.
Ln and e cancel each other out.
3x +2 = 3
3x = 1
x = 1/3
Answer:
5 times g EQ so the answer is 29
Using the z-distribution, the confidence interval is given by: (11.95, 12.65).
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:
In which:
- is the sample mean.
- is the standard deviation for the population.
In this problem, we have a 90% confidence level, hence, z is the value of Z that has a p-value of , so the critical value is z = 1.645.
The other parameters are given as follows:
Hence the bounds of the interval are:
