a)
- E =0.124
- Lower limit =3.026
- Upper limit = 3.274
b) Conditions: is understood to have a regular distribution of weights
c) Interpretation: 80 percent of the time, this range will include the actual average weight of Allen's hummingbirds, hence its reliability may be counted on
d) sample size .
Generally,
Here n = 17
T= 3.15
confidence level =c = 0.80
Here we will usethe z critical value.
z critical value for (1+c) /2 = (1+0.80)/2
z critical value for (1+c) /2= 0.9
Zc = 1.28
Critical value = 1.28
a) Margin of error (E) :
E =0.124
Margin of error = E =0.124
Lower limit = x-E
L= 3.15 - 0.124
L= 3.026
Lower limit =3.026
Upper limit = x + E
U= 3.15 + 0.124
U= 3.274
Upper limit = 3.274
The following is a confidence interval with a value of 80 percent for the mean weights of Allen's hummingbirds in the area under study: (3.02,3.28)
b) Conditions: is understood to have a regular distribution of weights
c) Interpretation: 80 percent of the time, this range will include the actual average weight of Allen's hummingbirds, hence its reliability may be counted on.
d) When is already known, the following equation may be used to determine the appropriate number of samples, n:
Margin of error = 0.13
Sample size (n):
n = 26.21
