Answer:

Step-by-step explanation:

Given the data:

Individual Method 1 Method 2 1 7 5 2 5 9 3 6 8 4 7 7 5 5 6

The point estimate for the difference between the means is the difference between the mean of method one and the mean of method 2

Determine if the two lines with the given slope are parallel, perpendicular, or neither. Circle your
Sati [7]

Answer:

As the lines are neither parallel nor perpendicular.

Therefore, the correct answer is ''neither''.

Hence, option C is correct.

Step-by-step explanation:

Given

m₁ = 3/2

m₂ = -3/2

We know that when two lines are parallel, they have equal slopes

But

m₁ ≠ m₂

3/2 ≠ -3/2

As the m₁ and m₂ are not equal.

Hence, the lines are not parallel.

We know that when two lines are perpendicular, the product of their slopes is -1.

Let us check the product of two slopes m₁ and m₂

m₁ × m₂ = 3/2 × -3/2

              = -9/4

              = -2.25

As

m₁ × m₂ ≠ -1

Thus, the lines are not perpendicular.

Conclusion:

As the lines are neither parallel nor perpendicular.

Therefore, the correct answer is ''neither''.

Hence, option C is correct.

Determine the median modles IQR and range for the data<br> 3,8,6,6,4,6,9,9,12
Nataly_w [17]

The median of the data is 6 and the IQR will be 4.

<h3>What are median and IQR?</h3>

The median is the number separating the greater half from the lower half of a sample data in probability theory and statistics. The interquartile range is a measure of statistical dispersion, or the spread of the data, in descriptive statistics.

To calculate the median first arrange the data in the increasing order and then find the mid value.

3,4,6,6,6,8,9,9,12

The middlemost value will be the median.

Median = 6

To calculate the IQR convert the data into lower limits and the upper limits from the median and then calculate the IQR.

3,4,6,6,   |6|     ,8,9,9,12

Lower               Upper

Q1 = (4 + 6)/2 = 5

Q2 = ( 9+9)/2 = 9

IQR = 9 - 5 = 4

Therefore, the median of the data is 6 and the IQR will be 4.
