The proportion of observations from a standard normal distribution that take values greater than 1.36 is:
1 answer:
Answer:
We are required to find the proportion of observations from a normal distribution that are greater than 1.36. Mathematically, it can be written as:
To find this proportion, we can use the standard normal table. Using the standard normal table, we have:
Therefore, the proportion of observations from a standard normal distribution that take values greater than 1.36 is 0.0869.

0.5
Step-by-step explanation:
Solution:-
- The sample mean before treatment, μ1 = 46
- The sample mean after treatment, μ2 = 48
- The sample standard deviation σ = √16 = 4
- For the independent samples T-test, Cohen's d is determined by calculating the mean difference between your two groups, and then dividing the result by the pooled standard deviation.
Cohen's d =
- Where, the pooled standard deviation (sd_pooled) is calculated using the formula:
- Assuming that population standard deviation and sample standard deviation are same:
SD_1 = SD_2 = σ = 4
- Then,
- The cohen's d can now be evaliated:
Cohen's d =
Answer:
Point lies on
axis and point
lies quadrant III.
Step-by-step explanation:
A coordinate plane is a plane that is divided into four quadrants by the coordinate axes.
Here, coordinate axes are axis and
axis.
Let's first mark the points in the coordinate plane.
See the attached figure.
From the figure, it can be observed that point lies on
axis and point
lies quadrant III.
