Answer:
(-3.07, 11.07)
Step-by-step explanation:
Given that a sports writer wished to see if a football filled with helium travels farther, on average, than a football filled with air. To test this, the writer used eighteen adult male volunteers. These volunteers were randomly divided into two groups of nine subjects each.
Group Group One Group Two
Mean 300.00 296.00
SD 8.00 6.00
SEM 2.67 2.00
N 9 9
The mean of Group One minus Group Two equals 4.00
standard error of difference = 3.333
df = 16
t = 1.2000
Margin of error = 3.3333* t critical = 3.3333*2.121
95% confidence interval of this difference: From -3.07 to 11.07
Answer:
The flow rate in dextrous solution is 0.117 litres per hour
Step-by-step explanation:
Given:
The volume of fluid which passes per unit time = 1.17 Litres
Time Period = 10 hour
To Find:
The Flow rate per hour = ?
Solution:
Flow rate is defined as rate at which the "{volume of fluid which passes per unit time"
Here the Flow rate is =
On substituting the values
The Flow rate is =
The flow rate is 0.117 litres per hour
Thus 0.117 litres of dextrous solution flows per hour.
