PLEASE ANSWER!!!!!

Answer:

There is a significant difference between the means of the two population

Step-by-step explanation:

The mean number of catfish caught daily at Lake Martin is 85, with the number of catfish ranging from 75 to 140.

Range = 140 - 75 = 65

The mean number of catfish caught daily at Smith Lake is 104, with the number of catfish ranging from 96 to 183.

Range = 183 - 96 = 87

Difference in mean = 104 - 85 = 19

If the confidence interval includes 0 we can say that there is no significant difference between the means of the two populations, at a given level of confidence

But by considering the mean difference and the value of range, we can say that

There is significant difference between the means of the two population

Last night, the two dinner specials at Bob's favorite restaurant were salmon filet and filet mignon. The restaurant served 70 sp

julia-pushkina [17]

Based on the given parameters, the number of filet mignon the restaurant served is 14

<h3>How to determine the number of filet mignon the restaurant served?</h3>

From the question, the given parameters are:

Dinner specials = salmon filet and filet mignon.

Dinner specials = 70 dinner specials

Salmon filets = 80%

This means that the proportion of filet mignon is

filet mignon = 100%- Salmon filets

This gives

filet mignon = 100%- 80%

Evaluate the difference

filet mignon = 20%

The number of filet mignon is calculated as:

filet mignon = 20% * Dinner specials

Substitute the known values in the above equation

filet mignon = 20% * 70

Express 20% as decimal

filet mignon = 0.20 * 70

Evaluate the product

filet mignon = 14

Hence, the number of filet mignon the restaurant served is 14

So, the complete parameters are:

Dinner specials = salmon filet and filet mignon.

Dinner specials = 70 dinner specials

Salmon filets = 80%

filet mignon = 14
