Tom [10]

Answer:

option A  is answer.

Step-by-step explanation:

Amount of interest earned for compounded monthly  for $1 = 1.040742

Amount of interest earned for compounded quarterly for $1= 1.040604

Difference for $1  =   1.040742 - 1.40604

                 =0.000138

Difference for $7000 = $7000x0.000138

                                    = 0.966

                                      or $0.96

Question 18 Item 18 The distribution of the number of moths captured per night by a certain moth trap is approximately normal wi
juin [17]

Answer:

Standard deviation 46.3

Step-by-step explanation:

A 28% of the distribution is equivalent to a z score of -0.5828, you can use a z table to find that.

Z score is calculated as follows:

z = \frac{x-\mu}{\sigma}

x is the number being evaluated

μ is the mean

σ is the standard deviation

And it is used to calculate how many standard deviations you are from the mean of the sample.

Replacing with the known information you can calculate the standard deviation:

\sigma=\frac{x-\mu}{z} =\frac{76-103}{-0.5828}= 46.3
