Rina8888 [55]

Answer:

d = 2\sqrt{29}

Step-by-step explanation:

d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d= \sqrt{(0-4)^2+(0-10)^2}\\d= \sqrt{(-4)^2+(-10)^2}\\d= \sqrt{16+100}\\d= \sqrt{116}\\d=2 \sqrt{29}

The owner of a local golf course wants to estimate the difference between the scores of golfers on his golf course and the score
Olenka [21]

Answer:

(8) The correct option is (3).

(2) The correct option is (1).

Step-by-step explanation:

(8)

The hypothesis can be defined as:

<em>H₀</em>: There is no difference between the two population means, i.e. <em>μ₁ </em>= <em>μ₂</em>.

<em>Hₐ</em>: There is a difference between the two population means, i.e. <em>μ₁ </em>≠ <em>μ₂</em>.

The decision rule of the test based on confidence interval is:

If the (1 - <em>α</em>) % confidence interval consists the null hypothesis value then the null hypothesis is not rejected. and vice-versa.

The 90% confidence interval for the paired difference between means is, (-3.31, 14.74).

The interval consists the null value, 0.

Thus, the null hypothesis was failed to be rejected.

<u>Conclusion:</u>

No significant difference exists between the average difference in scores and the differences were calculated as 0.

Thus, the correct option is (3).

(2)

A (1 - <em>α</em>) % confidence interval implies that there is (1 - <em>α</em>) % chance of the population parameter to be contained in this interval.

Or if 100 such intervals are constructed then (1 - <em>α</em>) of these intervals will consist the true parameter value.

The 99% confidence interval for the difference between means is, (-0.124, 13.85).

This interval implies that the true mean difference between the two populations lies in this interval with probability 0.99.

<u>Conclusion:</u>

We are 99% confident that the difference between the average age of all men and all women who play golf at the course is between -0.124 and 13.85.

Thus, the correct option is (1).
