1. Garbage Production. Based on a sample of 62 households, the mean weight of discarded plastic is 1.93 pounds and the standard

Contact [7]

Answer:

The answer is below

Step-by-step explanation:

Given that:

Mean (μ) = 1.93, standard deviation (σ) = 1.08 pounds, sample (n) = 62.

the mean weight of discarded plastic for all household is given by:

$\mu_x=\mu = 1.93\ pounds$

The standard deviation of discarded plastic for all household is given by:

$\sigma_x=\frac{\sigma}{\sqrt{n} } =\frac{1.08}{\sqrt{62} }=0.137\ pounds$

The confidence (c) = 90% = 0.9

α = 1 - c = 1 - 0.9 = 0.1

α/2= 0.1/2 = 0.05

The z score of 0.05 corresponds to the z score of 0.45 (0.5 - 0.05) which is 1.645. i.e. $z_\frac{\alpha}{2}=z_{0.05}=1.645$

The margin of error (E) = $z_{0.05}\frac{\sigma}{\sqrt{n} }=1.645*\frac{1.03}{\sqrt{62} }= 0.2256$

The confidence interval = $\mu \pm E=1.93 \pm 0.2256=(1.7044,2.1556)$

We are 90% confidence that the value is between 1,7044 and 2.1556
