Answer:
Given:
Mean, u = 2100
A golf magazine reports the mean gain to be $2100, while the teaching professional believes the average gain is not $2100.
Here the null and alternative hypotheses would be:
Null hypothesis:
H0: u = 2100
Alternative hypothesis:
Ha: u ≠ 2100
b) Here, given the level of significance, as 0.10. This means that:
The probability that the null hypothesis H0 is rejected when average gain is $2100 is 0.10
The slope of a line is
where is the difference and
and
are the values.
In this case, the difference in is 10 and the difference in
is 0
And division where the denominator being 0 leads to the answer being Undefined or Infinity as the line is directly on the axis.
Answer:
7, 7, 11 are the three numbers.
Step-by-step explanation:
<u>Given:</u>
Mode of the three numbers = 7
Range of numbers i.e. difference between the smallest and the largest number is = 4
Value of highest number card 7
As per the definition of Mode:
Mode is the number that occurs the most number of times in the given set of numbers. In other words, mode is the number whose frequency is the highest in the given set of numbers.
Here, we have three numbers and <em>mode is 7 </em>that means 7 occurs <em>at least two times </em>in the three numbers.
Also, we are given that <em>7 is not highest number</em>, plus <em>4 is the range </em>that means <em>7 occurs exactly two times </em>out of three numbers.
So, <em>two numbers are 7 and 7</em>.
<em>7 is not highest and 4 is the range, so third number = 7+4 = 11</em>
<em></em>
So, <em>the numbers on the cards are 7, 7 and 11.</em>
