Answer:
0.219 or 21.028%
Step-by-step explanation:
0.18 are defective, so
P(x=1) = 0.18
P(x=2) = 0.18^2 = 0.0324
P(x=3) = 0.18^3 = 0.005832
P(x=4) = 0.18^4 = 0.00104976
Then add them together: 0.21928176

Answer:
<em>The 95.7% confidence interval for the expected amount of garbage per bin for all bins in the city</em>
(48.937 , 50.863)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given data random sample of 46 bins, the sample mean amount was 49.9 pounds and the sample standard deviation was 3.641
<em>The sample size 'n' =46</em>
<em>mean of the sample x⁻ = 49.9</em>
<em>Standard deviation of the sample S = 3.641</em>
<u>Confidence intervals:</u><em>-</em>
<em>The 95.7% confidence interval for the expected amount of garbage per bin for all bins in the city</em>
<em></em>
<em></em>
<em>Degrees of freedom = n-1 = 46-1 =45</em>
<em>The tabulated value t₀.₉₆ = 1.794 ( from t-table)</em>
<em></em>
<em></em>
(49.9 -0.9630 , 49.9+0.9630)
(48.937 , 50.863)
<u>Conclusion:</u>-
<em>The 95.7% confidence interval for the expected amount of garbage per bin for all bins in the city</em>
(48.937 , 50.863)
