Assume the random variable x is normally distributed with mean u = 90 and standard deviation o=5. Find the indicated probability
Setler79 [48]

<u>Given</u>:

Let the random variable x is normally distributed with mean \mu=90 and \sigma=5

We need to determine the probability of P(X

<u>Probability of </u>P(X<u>:</u>

The formula to determine the value of P(X is given by

Z=\frac{X-\mu}{\sigma}

Thus, we have;

P(X

Simplifying, we get;

P(X

P(X

Using the normal distribution table, the value of -2 is given by 0.0228

P(X

Thus, the value of P(X is 0.0228

At winds speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. Wind speeds below 100
alisha [4.7K]

Answer:

Lower limit = 1007.95 cm/s

Upper limit = 1142.05 cm/s

Step-by-step explanation:

We have to calculate a 95% CI with population's standard deviation known.

The sample is size n=60, with mean M=1075.

The confidence interval can be expressed as:

M-z*\sigma/\sqrt{n} \leq\mu\leq M+z*\sigma/\sqrt{n}

For a 95% CI, the value of z=1.96.

1075-1.96*265/\sqrt{60} \leq\mu\leq 1075+1.96*265/\sqrt{60} \\\\1075-67.05 \leq\mu\leq 1075+67.05\\\\ 1007.95 \leq\mu\leq 1142.05
