Answer:
The 95% confidence interval for difference between population proportion is (-0.0194, -0.0006).
Step-by-step explanation:
The confidence interval for difference in population proportion formula is,
The given information is:
n₁ = 11508
X₁ = 921
n₂ = 4967
X₂ = 452.
Compute the sample proportion values as follows:
The critical value of <em>z</em> for 95% confidence interval is:
*Use the standard normal table.
Compute the 95% confidence interval for difference between proportions as follows:
Thus, the 95% confidence interval for difference between population proportion is (-0.0194, -0.0006).
Answer:
19.5 cm
Step-by-step explanation:
The median of a data set is the middle number. It can be easily found by crossing out the first value then the ending value, and you keep repeating that pattern. However, in this case, when we cross them out, we're left with the numbers 18 and 21. When we come across a problem like this, we find the mean of 18 and 21 by adding them up and then dividing them by 2. 18 + 21 is 39, and 39/2 is 19.5.
Therefore, the answer is 19.5 cm.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Y = |x| has a v-shaped graph that opens upward; y = -|x| has a v-shaped graph that opens downward.
The given equation has a v-shaped graph that opens downward, with vertex at (-2,3).
