Amanufacturer knows that their items have a normally distributed length, with a mean of 13.2 inches, and standard deviation of 2.2 inches. if one item is chosen at random, what is the probability that it is less than 13.4 inches long?

0.5358

Step-by-step explanation:

Given

mean = μ = 13.2 inches

and

SD = σ = 2.2 inches

We have to find z-score for the given value 13.4 first

z-score = (x-μ)/σ

=  (13.4-13.2)/2.2

=0.2/2.2

=0.0909

We have to find the area to the left of given z-score

The area to the left is 0.5358

So, the probability of choosing an item with length less than 13.4 is 0.5358 ..

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
