A company that translates books between various languages is currently testing a​ computer-based translation service. The founde

r of the company expects the computer program to make some​ errors, but then so do human translators. The computer error rate is supposed to be an average of 2 per 500 words of translation. Suppose the company founder randomly selects a ​3,000-word passage. Assume that the Poisson distribution applies and that the computer error rate is actually 2 errors per 500 words. Complete parts a through c.
a. Determine the probability that no errors will be found.
The probability is ___. Round to four decimal places as​ needed.)

b. Calculate the probability that more than 30 errors will be found.
The probability is ___. ​(Round to four decimal places as​ needed.)

c. Find the probability that fewer than 15 errors will be found.
The probability is ___. ​(Round to four decimal places as​ needed.)

260

650 times 0.4 (20%+40%)
Since the kids and women are 60%
100%-60%= 40% so 40% were men

I’m not sure but I think it’s right hope it helps tho

I started this and got distracted and never finished and it timed out. Focus Dean.

It's not the best graph; I assume the origin is the apparent origin and the y axis numbers go with the line above them.

This graph is M(V), M(V) is mass in kg of bucket with water volume V in liters

a) the mass of an empty bucket

That's the y intercept, M(0), eyeballing it around .7 kg

Answer: .7 kg

b) the mass of the bucket containing 1 liter of liquid

That's M(1), looks like 1.3 or so

Answer: 1.3 kg

c) the mass of one liter of liquid

That's the difference, M(1)-M(0), about .6 kg. We can get a better estimate from a longer slope, say (.5,1) to (3,3), (3-1)/(3-.5) = .8 kg.

Answer : 0.8 kg

d) the volume of the liquid in the bucket, if the total mass of bucket with the liquid is 3 kg.

Solve M(V)=3

That has a solution from the graph V=3.

Answer: 3 liters

The average weight of a bar of soap should be 6.4 ounces with a standard deviation of 0.2 ounces. A sample of 20 bars of soap fo
-Dominant- [34]

Answer:

The testing statistic is -2.237

Step-by-step explanation:

Test statistic (z) = (sample mean - population mean) ÷ (population standard deviation/√n)

sample mean = 6.3 ounces

population mean = 6.4 ounces

population standard deviation = 0.2 ounces

n (sample size) = 20

z = (6.3 - 6.4) ÷ (0.2/√20) = -0.1 ÷ 0.0447 = -2.237
