A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado lengths​ (miles) to test the claim that the mean tornado length is greater than 2.2 miles. Use a 0.05 significance level. Identify the null and alternative​ hypothesis, test​ statistic, P-value, and state the final conclusion that addresses the original claim. LOADING...

Answer 1

Answer:

The answer is:

[tex]H_0:\mu=2.2\\H_1:\mu> 2.2[/tex]

Explanation:

[tex]H_0:\mu=2.2\\H_1:\mu> 2.2[/tex]

The test value of statistic t= [tex]\frac{\bar x-\mu}{\frac{s}{\sqrt{n}}}[/tex]

                                               [tex]=\frac{2.31688-2.2}{0.206915}\\\\=0.56[/tex]

The value of P = P(T>0.56)

                          =1-P(T<0.56)

                          =1-0.712

                          =0.288

Since the P value exceeds its mean value (0.288>0.05), the null assumption must not be rejected.  Don't ignore H0. This assertion, it mean length of the tornado is greater than 2.2 miles also isn't backed by enough evidence.

Which is the right way to give comment if you are using Internet explorer as the browser? a) <!-- My First Webpage --> b) <comment> My First Webpage </comment>

Answers

Answer:

(a) <!-- My First Webpage -->

Explanation:

Comments in programming languages are chunks of texts, written as part of program code, that are not executed as actual code but rather used for making the program code easily readable and understandable. They allow programmers to explain certain lines of a program code.

Every programming language has its own way of representing comments. In HTML - HyperText Markup Language - comments are written between the following tags :

<!--

and

-->

For example, to put the text "My comment goes here" in a comment, we write:

<!-- My comment goes here -->

From the question, the text to be put is:  "My First Webpage". Therefore, we write;

<!-- My First Webpage -->

If 2x+9 Read the following excerpt from The Gift of the Magi and answer the question. For there lay The Combs--the set of combs, side and back, that Della had worshipped long in a Broadway window. Beautiful combs, pure tortoise shell, with jewelled rims--just the shade to wear in the beautiful vanished hair. They were expensive combs, she knew, and her heart had simply craved and yearned over them without the least hope of possession. And now, they were hers, but the tresses that should have adorned the coveted adornments were gone. But she hugged them to her bosom, and at length she was able to look up with dim eyes and a smile and say: "My hair grows so fast, Jim! And them Della leaped up like a little singed cat and cried, "Oh, oh!" Jim had not yet seen his beautiful present. She held it out to him eagerly upon her open palm. The dull precious metal seemed to flash with a reflection of her bright and ardent spirit."Isn't it a dandy, Jim? I hunted all over town to find it. You'll have to look at the time a hundred times a day now. Give me your watch. I want to see how it looks on it." Instead of obeying, Jim tumbled down on the couch and put his hands under the back of his head and smiled."Della," said he, "let's put our Christmas presents away and keep 'em a while. They're too nice to use just at present. I sold the watch to get the money to buy your combs. And now suppose you put the chops on." The magi, as you know, were wise men--wonderfully wise men--who brought gifts to the Babe in the manger. They invented the art of giving Christmas presents. Being wise, their gifts were no doubt wise ones, possibly bearing the privilege of exchange in case of duplication. And here I have lamely related to you the uneventful chronicle of two foolish children in a flat who most unwisely sacrificed for each other the greatest treasures of their house. But in a last word to the wise of these days let it be said that of all who give gifts these two were the wisest. O all who give and receive gifts, such as they are wisest. Everywhere they are wisest. They are the magi.
