I believe B and D because a minus multiplied by a positive gives you a negative answer. Therefore, your answer would equal to -36.

Hope this helped :)

Construct the 95% confidence interval for the population mean using the appropriate distributions. a. A random sample of 50 peop

SSSSS [86.1K]

Answer: 95% confidence interval would be (26.01,29.39).

Step-by-step explanation:

Since we have given that

n = 50

Mean = 27.7

Standard deviation = 6.12

We need to construct 95% confidence interval for the population.

so, z = 1.96

So, it becomes,

$\bar{x}\pm z\times \dfrac{\sigma}{\sqrt{n}}\\\\=27.7\pm 1.96\times \dfrac{6.12}{\sqrt{50}}\\\\=27.7 \pm 1.69\\\\=(27.7-1.69,27.7+1.69)\\\\=(26.01,29.39)$

Hence, 95% confidence interval would be (26.01,29.39).

How to find exponential distribution Mean and variance

Rufina [12.5K]

Answer:

To calculate the mean, you're multiplying every element by its probability (and summing or integrating these products). Similarly, for the variance you're multiplying the squared difference between every element and the mean by the element's probability. and X = {1, 2, 3}, then Y = {1, 4, 9}.
