Weston completed a hypothesis test and found that he could not reject the null hypothesis. Which of the following is a valid reason for his conclusion? A.The z-statistic is less than 0.
B.The z-statistic lies in the critical region.
C.The z-statistic is greater than 0.
D.The z-statistic lies outside the critical region.

Answers

Answer 1
Answer:

Answer: D.The z-statistic lies outside the critical region.


Step-by-step explanation:

When we run a hypothesis test , the result of that test will be a  probability value. The probability value is represented by a “p value” .

It tells us if hypothesis statement is probably true or not.

If the value falls in the rejection region, it means you have statistically significant results; You can reject the null hypothesis.

If the p-value falls outside the rejection region, it means your results aren’t enough to throw out the null hypothesis.

Hence, if Weston ound that he could not reject the null hypothesis. The z-statistic lies outside the critical region would be the valid reason for his conclusion.
Answer 2
Answer: The right answer for the question that is being asked and shown above is that: "D.The z-statistic lies outside the critical region." Weston completed a hypothesis test and found that he could not reject the null hypothesis. A valid reason for his conclusion is that D.The z-statistic lies outside the critical region.

In Volleyball , players serve the ball to the opposing team . If the opposing team fails to hit the ball , the services is called an ace . A player's ace average is the number of aces served divided by the number of games played . A certain player has an ace average of 0.3 and has played in 70 games this season . How many aces has the player served ?

Answers

To solve, I would write an equation like this: 0.3=x/70 , where x is the number of aces divided by 70 games and 0.3 is his ace average.

0.3=x/70
x=70x0.3
  =21

The player has served 21 aces.

Check:
21/70
=0.3

Final answer:

To find the number of aces the player has served, we can use the formula: Ace Average = Number of Aces / Number of Games Played. Given that the player has an ace average of 0.3 and has played in 70 games this season, the player has served 21 aces.

Explanation:

To find the number of aces the player has served, we can use the formula:

Ace Average = Number of Aces / Number of Games Played

Given that the player has an ace average of 0.3 and has played in 70 games this season, we can set up the following equation:

0.3 = Number of Aces / 70

Multiplying both sides by 70, we get:

21 = Number of Aces

Therefore, the player has served 21 aces this season.

394.6 divided by 9 using compatible numbers to estimate the quotient?

Answers

394.6 / 9 = 43.84

Compatible numbers:

400 / 10 = 40

Compatible numbers are numbers that can quickly be solved mentally. The quotient would only be an estimate since we only rounded the number to the nearest compatible number.

394.6 is nearer to 400 while 9 is closer to 10. Both numbers 400 and 10 are compatible because they can be solved quickly doing mental calculations.
