Step-by-step explanation:

Golf-course designers have become concerned that old courses are becoming obsolete since new technology has given golfers the ability to hit the ball so far. Designers, therefore, have proposed that new golf courses need to be built expecting that the average golfer can hit the ball more than 230 yards on average. A random sample of 177 golfers show that their mean driving distance is 230.7 yards, with a standard deviation of 41.8.1. Set up the null and alternative hypotheses to test for the designers belief.
a. H0 : µ ≥ 230 versus Ha : µ < 230
b. H0 : µ = 230.7 versus Ha : µ ≠ 230.7
c. H0 : µ ≥ 230.7 versus Ha : µ < 230.7
d. H0 : µ ≤ 230.7 versus Ha : µ > 230.7
e. H0 : µ ≤ 230 versus Ha : µ > 230
2. Find the value of the standardized test statistic.
a. 0.125
b. -0.125
c. 0.223
d. -0.7
e. 0.7
3. Find the P-value for the above mentioned test.
a. 0.8237
b. 0.0228
c. 0.5871
d. 0.4118
e. 0.0871

Answers

Answer:

a) e) H0 : µ ≤ 230 versus Ha : µ > 230

b) $t=(230.7-230)/((41.8)/(√(177)))=0.223$

c. 0.223

c) $p_v =P(t_((176))>0.223)=0.4118$

d. 0.4118

Step-by-step explanation:

Information given

$\bar X=230.7$ represent the sample mean

$s=41.8$ represent the sample standard deviation

$n=177$ sample size

$\mu_o =230$ represent the value to verify

t would represent the statistic

$p_v$ represent the p value

Part a

We want to verify if the true mean is higher than 230 yards, the system of hypothesis would be:

Null hypothesis: $\mu \leq 230$

Alternative hypothesis: $\mu > 230$

The best option would be:

H0 : µ ≤ 230 versus Ha : µ > 230

Part b

The statistic is given by:

$t=(\bar X-\mu_o)/((s)/(√(n)))$ (1)

Replacing the info given we got:

$t=(230.7-230)/((41.8)/(√(177)))=0.223$

Part c

The degrees of freedom are:

$df=n-1=177-1=176$

The p value would be given by:

$p_v =P(t_((176))>0.223)=0.4118$

d. 0.4118

Question 20Identify the area of the polygon with vertices B (3, 2), C (7,-2), D (2,-4), and E (1, -2).

Answers

Answer:

(d) A = 18 units²

Step-by-step explanation:

Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...

A = 1/2bh

Then the sum of the areas of the two triangles is ...

A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18

The area of the polygon is 18 square units.

Answer: A=18units2

Step-by-step explanation:

I said 17 before and got it wrong lol.

Next time I said 18 cuz it seemed like the closest when I estimated what it looked like the units it covered, so it's right:)

Answer:

3.84 units

Step-by-step explanation:

By the properties of angle bisectors, ...

WZ/ZX = WY/YX

Solving for WY, we have ...

WY = (YX)(WZ)/(ZX) = (6.5/6)(WZ)

The length YZ is ...

YZ = 8 = WY +WZ

8 = (6.5/6)(WZ) +WZ = 12.5/6(WZ) . . . . substitute for WY

WZ = 8(6/12.5) . . . . multiply by 6/12.5

WZ = 3.84

12,60,108

12,72,96

12,84,84

36,60,84

36,72,72

48,48,84

48,60,72

60,60,60

Hence the probability is 1/19 or 0.0526

Final answer:

An equiangular triangle has all angles equal to 60 degrees. A triangle with angles that are multiples of 12 can be equiangular triangle only if each angle is 60 degrees. The probability of this is low due to multiple possibilities of multiple of 12.

Explanation:

In mathematics, a triangle is defined as equiangular if all its angles are equal. For a triangle to be equiangular, each angle must measure 60 degrees because the sum of all angles in a triangle is always 180 degrees.

Note, if each angle of a triangle is a multiple of 12, the only way it can be an equiangular triangle is if each angle measures 60 degrees (which is indeed a multiple of 12). Therefore, for a triangle with angles that are multiples of 12 to be an equiangular triangle, each angle must be 60 degrees.

However, multiple possibilities exist for angles of a triangle that are a multiple of 12, for instance, 12, 72, 96 or 24, 36, 120 etc. Therefore the probability that randomly picked triangle with the given condition is equiangular is relatively very low.
