Answer:
The confidence interval has a lower limit of 0.546 and an upper limit of 0.675.
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 z-score that has a p-value of 
.
In 2017, a random sample of 154 individuals who graduated from high school 12 months prior was selected. From this sample, 94 students were found to be enrolled in college or a trade school.
This means that 
90% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The confidence interval has a lower limit of 0.546 and an upper limit of 0.675.
Answer:
74
Step-by-step explanation:
the top two are 5 cm each angled sides and it completely added up to 74
For one boy it would be 4/5, but since its two boys, then it would be 4/5 for the first boy and 3/5 for the second because before any of the names are drawn, there are 4 boys names in the bag and 5 girls names. For the second boy, the would be 3 boys names and 5 girls names in the bag (assuming that the first name drawn was a boys).
Answer:
C. 55s
Step-by-step explanation:
I'll refer to Wyndham as W and Michael as M.
Also, we will be assuming constant speed for both runners.
So, first of all, W ran with a speed of 8m/s;
400m/50s = 8 m/s
M ran with speed 9.2635.... m/s;
400m/43.18s = 9.26.... m/s
The difference is 1.26.... m/s, meaning every second, the distance between M and W would increase by 1.26.....m, starting from 0 at the start line;
9.26... - 8 = 1.26....
So, to find the desired distance, we simply multiply 1.26... by 43.18;
1.26... × 43.18 = 54.560....
(Rounded up to 55s)
