Answer:
The smaller the MAD the less variability, meaning a bigger MAD means more distance between data.
Step-by-step explanation:
In the expression 4(x), 4 represents the number of legs, and x represents the height of the coffee table.
Altogether this expression shows the total length of all legs from the coffee table and kitchen table combined.
Answer:
We conclude that there has been a significant reduction in the proportion of females.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 400
p = 50% = 0.5
Alpha, α = 0.05
Number of women, x = 118
First, we design the null and the alternate hypothesis
This is a one-tailed test.
Formula:
Putting the values, we get,
Now, we calculate the critical value.
Now, 
Since the calculated z-statistic is less than the critical value, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Thus, there has been a significant reduction in the proportion of females.
