Hello from MrBillDoesMath!

Answer:

a^6 + 4 a^5 + 5 a^4 - 5 a^2 - 4 a - 1

Discussion:

You may need to clean things up a bit but suppose that

S(1) = a-1

S(2) = a^2 -1

Since this is a geometric series, the geometric ratio is given by

S(2)/ S(1) = (a^2 -1)/ (a-1)

= (a+1)(a-1)/ (a-1)

= a+1

Conclusion:

S(2) = (a+1) S(1) = (a+1) (a-1)

S(3) = (a+1) S(2) = (a+1) (a+1) (a-1) = (a+1)^ (3-1) (a-1)

S(4) = (a+1) S(3) = (a+1) * (a+1)^2 (a-1) ) = (a+1)^(4-1) (a-1)

in general.....

S(n) = (a+1)^ (n-1) (a-1)

S(6) = (a+1)^ (6-1) (a-1)

= (a-1) (a+1) ^ 5

= a^6 + 4 a^5 + 5 a^4 - 5 a^2 - 4 a - 1

Hope I didn't screw something here!

Thank you,

MrB

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

lisov135 [29]

Answer:

The null and alternative hypothesis are:

$H_0:\mu =2.6\\H_a:\mu >2.6$

There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles

Step-by-step explanation:

Consider the provided information.

The claim that the mean tornado length is greater than 2.6 miles.

If there is no statistical significance in the test then it is know as the null which is denoted by $H_0$ , otherwise it is known as alternative hypothesis which denoted by $H_a$ .

Therefore, the required null and alternative hypothesis are:

$H_0:\mu =2.6\\H_a:\mu >2.6$

significance level α =0.05

From the given table the test statistic T=2.230166

P-value is 0.0131

0.0131<0.05

P value is less than the significance level, so reject the null hypothesis.

There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
