A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado l

engths​ (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:

The answer is:

H_0:\mu=2.2\\H_1:\mu> 2.2

Explanation:

H_0:\mu=2.2\\H_1:\mu> 2.2

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

                                               =\frac{2.31688-2.2}{0.206915}\\\\=0.56

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.

Over the past three hours the pressure has been steadily increasing at a rate of what
Lyrx [107]

Answer:

We need to find first the location, and then we need to note down the barometric pressure of each hour in tenth place without decimal like 1013.3 mb is equal to 133 and so on. And the rate can be steadily increasing, steady, steadily decreasing, steadily increasing and then falling, steadily falling and then increasing, and so on. To find the rate of increase in barometric pressure, we need to find the rate of change of barometric pressure, and this will be clear if we prepare the chart of the barometric pressure of each hour during the past three hours. The graph plotted will give us a clear indication through its slope.

What is stored in alpha after the following code executes?
Andreas93 [3]

Answer:

3. alpha = {1, 5, 6, 7, 5}

Explanation:

Initially, we have that:

alpha[0] = 1;

alpha[1] = 2;

alpha[2] = 3;

alpha[3] = 4;

alpha[4] = 5;

For j higher than 2, we have that:

alpha[j - 1] = alpha[j] + 2;

So

j = 3

a[2] = alpha[3]+2 = 4 + 2 = 6;

j = 4

a[3] = alpha[4]+2 = 5+2 = 7;

The correct answer is:

3. alpha = {1, 5, 6, 7, 5}
