Answer:
89
Step-by-step explanation:
This is how to round 88.6 to the nearest whole number. In other words, this is how to round 88.6 to the nearest integer. 88.6 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point: Integer Part: 88 Fractional Part: 60 Our goal is to round it so we only have an integer part using the following rules: If the first digit in the fractional part of 88.6 is less than 5 then we simply remove the fractional part to get the answer. If the first digit in the fractional part of 88.6 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer. The first digit in the fractional part is 6 and 6 is 5 or above. Therefore, we add 1 to the integer part and remove the fractional part to get 88.6 rounded to the nearest whole number as: 89
75,88,90,96,98,100
minimum = 75
Q1 = 88.....this is where the box begins
Q2 (the median) = (90 + 96) / 2 = 186/2 = 93....this is the line in the box
Q3 = 98....this is where the box ends
maximum = 100

Answer:
990
Step-by-step explanation:
M/J = 2/7
J = 3/4 L
L = M + 396
7M = 2J
J = 3.5M
3.5M = 3/4 L
L = 4/3(3.5M)
L = 14/3 M
14/3 M = M + 396
11/3 M = 396
M = 3/11 × 396
M = 108
L = M + 396
L = 108 + 396
L = 504
J = 3/4 L
J = 3/4 × 504
J = 378
M + L + J = 108 + 504 + 378 = 990

The correct option is D
Step-by-step explanation:
From the question we are told that
The margin of error is 
The largest value is k = 15
The smallest value is u = 7
From the question we are told the confidence level is 95% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally population standard deviation estimate is mathematically represented as
Here the Range is mathematically represented as

Generally to obtain a conservatively small sample size the population standard deviation estimate becomes
=> 
=> 
=> 
Generally the conservatively small sample size is mathematically evaluated as
