Answer:

20 measured and 10 used

Step-by-step explanation:

Total number of participants is given as n = 10.

Number of treatment conditions = 2

Total measurements is therefore 2 × 10 = 20

Therefore, in total, 20 scores will be measured in the given study.

Now there are two samples and for each sample, for each sample we need to calculate the mean = Sum of value(measures)/Number of measures

                     mean = Sum of value(measures)/10

Therefore,  we are going to have 20 measured and 10 used to calculate the sample mean and the sample variance.

A boat takes 5 hours to go upstream. It can go 50 miles downstream in the same time. Find the rate of the current in the rate of
natka813 [3]

Answer:

Rate of current is 3 miles per hour and speed of the boat in still water is 7 miles per hour.

Step-by-step explanation:

This question is incomplete; find the complete question here.

A boat travels 20 miles upstream in 5 hours. Going downstream, it can travel 50 miles in the same amount of time. Find the speed of the current and the speed of the boat in still water.

Let the speed boat in the still water = x miles per hour

and the speed (rate) of the current = y miles per hour

Speed of the boat to go upstream (against the current) will be = (x - y)miles per hour

Since boat takes 5 hours downstream to travel 50 miles then from the formula,

\text{Time}=\frac{\text{Distance}}{\text{Speed}}

5=\frac{50}{(x+y)}

(x + y) = 10 -------(1)

Boat takes 5 hours to travel 50 miles upstream then,

\text{Time}=\frac{\text{Distance}}{\text{Speed}}

5 = \frac{20}{(x-y)}

x - y = 4 -----(2)

By adding equation (1) and question (2)

(x + y) + (x - y) = 14

2x = 14

x = 7 miles per hour

From equation (1),

7 + y = 10

y = 3 miles per hour

Therefore, Rate of current is 3 miles per hour and speed of the boat in still water is 7 miles per hour.
