Answer:
This means that we are 95% confident that the mean change in HDL (high-density lipoprotein, or "good" cholesterol) of adults eating raw garlic six days a week for six months is between plus or minus 5 milligrams per deciliter of blood (mg/dl) to the sample mean.
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
For 95% confidence interval, it means that we are 95% confident that the mean of the population is between the given upper and lower bounds(margin of error) of the confidence interval.
For the case above, the interpretation of the 95% confidence interval is that we are 95% confident that the mean change in HDL (high-density lipoprotein, or "good" cholesterol) of adults eating raw garlic six days a week for six months is between plus or minus 5 milligrams per deciliter of blood (mg/dl) to the sample mean.
Answer:
there are 36 possible bag lunches
Step-by-step explanation:
Assuming that the possible sandwiches do not depend on the selection of the chips and fruits ( and the same for chips or fruits respect to the other food in the bag)
then
number of possible bag lunches= possible sandwiches * possible chips* possible fruits = 3 * 4 *3 = 36
then there are 36 possible bag lunches
Answer:
time = 4.4 s
horizontal distance = 488.8 m
Step-by-step explanation:
Height, h = 4 ft
Angle, A = 32 degree above X axis
velocity, u = 131 ft/s
Let the time taken is t.
Use second equation of motion

So, time is 4.4 s.
The horizontal distance is
d = u cos A t
d = 131 cos 32 x 4.4 = 488.8 m
