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).

Divide $2.50 in a ratio of 4:1
hram777 [196]

Step-by-step explanation:

4x + x = 2.5 \\  \\  \therefore \: 5x = 2.5 \\  \\  \therefore \: x =  \frac{2.5}{5}  = 0.5 \\  \\  \therefore \:  4x = 4 \times 0.5 = 2

Hence, 2.50 in the ratio 4 : 1 can be divided as 2 and 0.5

The company has a sample box that is a rectangular prism with a rectangular base with an area of 231⁄3 in2. The height of the pr
vodka [1.7K]

Answer:

29.17 in^3

Step-by-step explanation:

We are given that  

Base area of sample box,a=23\frac{1}{3} in^2=\frac{70}{3}in^2

Height of the sample box,h=1\frac{1}{4}=\frac{5}{4} in

We have to find the volume of the sample box.

We know that  

Volume of rectangular prism,V=ah

Where a=Area of base

Using the formula  

Volume of sample box=\frac{70}{3}\times \frac{5}{4}=29.17 in^3

Hence, the volume of the sample box=29.17 in^3
