Answer:
The 98% confidence interval on the population proportion of people who like the new flavor is (0.8237, 0.8763).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
98% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 98% confidence interval on the population proportion of people who like the new flavor is (0.8237, 0.8763).
Answer:
AB = 
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 2, 1) and (x₂, y₂ ) = B(3, 4)
d = 
= 
= 
=

Answer:
a) bb, bg, gb, gg
b) 25% probability of getting two green dash eyed children.
c) 50% probability of getting exactly one blue dash eyed child and one green dash eyed child.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Total of eight outcomes.
a. Construct a similar sample space for the possible eye color outcomes (using b for blue dash eyed and g for green dash eyed) of two children.
bb, bg, gb, gg
b. Assuming that the outcomes listed in part (a) were equally likely, find the probability of getting two green dash eyed children.
Four outcomes.
Of those, in one(gg), you get two green dash eyed children.
1/4 = 0.25
25% probability of getting two green dash eyed children.
c. Find the probability of getting exactly one blue dash eyed child and one green dash eyed child.
In two of those(bg and gb) you get one blue dash eyed child and one green dash eyed child.
2/4 = 0.5
50% probability of getting exactly one blue dash eyed child and one green dash eyed child.
