Find the volume of a rectangular prism that has a length of 14 yards, a width of 5 yards and a height of 8 yards.

Researchers found a linear relationship between tail-feather length (in mm) and weight (in g) in a random sample of 20 male long

Dafna11 [192]

Answer:

Step-by-step explanation:

As far as I know, this question is not correct. I have the searched the internet and found a similar question which makes sense. In the correct question, 95% Confidence Interval is already given calculated from the software and

95% prediction interval is asked (PI) for the weight of one male long tailed finch weighing 20 g.

We have this data given in the correct question found on internet. And they have calculated this data using software:

New Obs = 20

Fit = 92.34

SE Fit = 5.26

95% Confidence Interval = (81.29, 103.38)

95% Prediction Interval = (67.61, 117.06)

Now, Just look at the prediction interval:

Now the formula for Prediction Interval = Point Estimate ± Margin of Error

Upper limit for prediction interval = 117.06

lower limit = 67.61

Formula for point estimate = (Upper + Lower)/2

Point Estimate = (117.06 + 67.61)/2

Point Estimate = 92.34

Formula for margin of error = (Upper - Lower)/2

Margin of Error = (117.06 - 67.61)/2

Margin of Error = 24.72

Formula for Prediction Interval = Point Estimate ± Margin of Error

PI = 92.34 ± 24.72

Customers arrat a service window according to a poisson process with an average of 0.2 per minute.

suter [353]

Answer:

Step-by-step explanation:

Given that customers arrat a service window according to a poisson process with an average of 0.2 per minute

= 12 per hour.

a) the probability that the time between two successive arrivals is less than 6 minutes

= For one hour more than 60/6 =10 customers arrive.

P(X>10) = 0.6528

b) Prob that there will be exactly three arrivals during a given 10-minute period

P(x=3) for average 2

= 0.1804

X-y=-3 Anyone know how to do this ?

horsena [70]

X - y = -3

Move constant to the left by adding its opposite to both sides

x - y + 3 = -3 + 3

The sum of two opposites equals

your answer would be: x - y + 3 = 0

Apple weights are normally distriuted with a mean 0.33 pounds and and standard deviation of 0.06 pounds. Jermaine went to the st

maksim [4K]

Using the normal distribution, it is found that 10.56% of the apples weigh less than Jermaine's apple.

--------------------

In a normal distribution with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

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

It measures how many standard deviations the measure X is from the mean.
After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X, that is, the proportion of measures that are less than X.

In this problem:

Mean of 0.33 pounds, thus $\mu = 0.33$ .
Standard deviation of 0.06 pounds, thus $\sigma = 0.06$ .
The proportion that is less than 0.25 pounds is the p-value of Z when X = 0.25, thus:

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

$Z = \frac{0.25 - 0.33}{0.06}$

$Z = -1.25$

$Z = -1.25$ has a p-value of 0.1056.

0.1056 x 100% = 10.56%.

10.56% of the apples weigh less than Jermaine's apple.
