The amount of tea leaves in a can from a production line is normally distributed with = 110 grams and = 25 grams. A sample of 25 cans is to be selected. a. What is the probability that the sample mean will be between 100 and 120 grams? b. 95% of all sample means will be greater than how many grams? hwteazbjai. join her​

Answers

Answer 1

95% of all sample means will be greater than 69 grams

Z score

Z score is used to determine the number of standard deviations the raw score is above or below the mean. It is given by:

x = raw score, μ = mean, σ = standard deviation, hence:

z = (x - μ)/σ

μ = 110, σ = 25

For x = 100:

z = (100 - 110) / 25 = -0.4

For x = 120:

z = (120 - 110) / 25 = 0.4

P(-0.4 < z < 0.4) = P(z < 0.4) - P(z < -0.4) = 0.6554 - 0.3446 = 31.08%

P(z > z*) = 0.95

1 - P(z < z*) = 0.95

P(z < z*) = 0.05

z* = -1.65

-1.64 = (x - 110)/25

x =69

95% of all sample means will be greater than 69 grams.

Answer:

What does the Europeans want from these countries? Raw Materials. Why? During that time Great Britain industrial revolution was going on. You need raw materials like Iron to create products to sell. Boost europeans economy, so they exploit other countries.

Europeans believe they have a far superior govt. than other countries, so they will "parent" other countries. Another way is promising them technology, medicine and education.

Explanation:

I think its D because it can't be C or B and I don't think its A

it was the Vikings who inhabited the current day western part Russia in 800 CE.

Who are the Vikings?

Contrary to some popular conceptions of the Vikings, they were not a “race” linked by ties of common ancestry or patriotism, and could not be defined by any particular sense of “Viking-ness.” Most of the Vikings whose activities are best known come from the areas now known as Denmark, Norway and Sweden, though there are mentions in historical records of Finnish, Estonian and Saami Vikings as well. Their common ground–and what made them different from the European peoples they confronted–was that they came from a foreign land, they were not “civilized” in the local understanding of the word and–most importantly–they were not Christian.
