Step-by-step explanation:
Curtis is playing a trivia game.
Number of points earned for each correct answer = 2
Number of points lost for each correct answer = 0.25
Given that:
Number of correct answers given by Curtis = 21
Number of wrong answers given by Curtis = 4
To find:
Total score of the game by Curtis?
Solution:
First of all, let us find the points earned by correct answers.
Points earned by correct answers = Number of correct answers multiplied by Points earned on one correct answer.
Points earned by correct answers = 21 2 = 42
Now, let us find the points to be lost by wrong answers.
Points lost by wrong answers = Number of wrong answers multiplied by Points lost on one correct answer.
Points lost by wrong answers = 4 0.25 = 1
The score of the game can be calculated by subtracting the points lost from the points earned.
Score = 42 - 1 = <em>41</em>
Answer:
The adult male foot length of 24.3 cm is significantly low.
Step-by-step explanation:
We have been given that a group of adult males has foot lengths with a mean of 26.88 cm and a standard deviation of 1.13 cm. We are asked to find the range rule of thumb to determine whether he adult male foot length of 24.3 cm significantly low or significantly high.
The range rule of thumb states that usual values in a normal standard deviation lies within 2 standard deviation from mean that is , where
.
Let us find the range of possible values.
Since 24.3 is less than lower value of range (26.62), therefore, the adult male foot length of 24.3 cm is significantly low.
