Answer:
The correct option is C 20.1%.
Step-by-step explanation:
The probability distribution chart representing the opinions of employed adult women about government funding for day care is as follows:
Rating (<em>X</em>) Probability (<em>p</em>)
1 0.110
2 0.206
3 0.464
4 0.201
5 0.119
The ratings are defined as follows:
1: too little
2: helpful but not enough
3: make a difference but insufficient
4: sufficient
5: generous
The probability of women who think that the support is sufficient is, 0.201.
The percentage is: 0.201 × 100 = 20.1%
Thus, the percentage of women who think that the support is sufficient is 20.1%.
The correct option is C.
Answer:
3/
8 is greater than 3/
12 because if you cross multiply 12 times 3 is 36 and 3 times 8 is 24
Step-by-step explanation:
Using the z-distribution, it is found that the 95% confidence interval for the difference is (-1.3, -0.7).
<h3>What are the mean and the standard error for each sample?</h3>
Considering the data given:
<h3>What is the mean and the standard error for the distribution of differences?</h3>
The mean is the subtraction of the means, hence:
The standard error is the square root of the sum of the variances of each sample, hence:
<h3>What is the confidence interval?</h3>
It is given by:
We have a 95% confidence interval, hence the critical value is of z = 1.96.
Then, the bounds of the interval are given as follows:
