Explanation

حقوق العباد کا مطلب ہے اللہ کے بندوں (انسانوں) کے ایک دوسرے پر حقوق۔

ان میں والدین، ہمسایہ، دوست، رشتہ دار اور دیگر انسانوں کے ساتھ حسن سلوک شامل ہے۔

Explanation

Step 1: Calculate the mean of the marks.

Mean = (6 + 8 + 10 + 12 + 4 + 20) / 6

= 60 / 6

= 10

Step 2: Calculate the mean deviation.

Mean Deviation = (|6-10| + |8-10| + |10-10| + |12-10| + |4-10| + |20-10|) / 6

= (4 + 2 + 0 + 2 + 6 + 10) / 6

= 24 / 6

= 4

Step 3: Calculate the coefficient of dispersion.

Coefficient of Dispersion = Mean Deviation / Mean

= 4 / 10

= 0.4

Explanation

The standard deviation of a binomial distribution is indeed √npq, where:

• n is the number of trials
• p is the probability of success
• q is the probability of failure (q = 1 - p)

The formula for the standard deviation of a binomial distribution is:

σ = √npq

This represents the spread or dispersion of the distribution.

Explanation

Geometric Mean = ∛(2 × 4 × 8)

= ∛64

= 4

Explanation

A bimodal distribution has two modes, meaning two values occur with the highest and equal frequency.

It indicates the presence of two peaks in the data set.

Explanation

A small standard deviation means the data is tightly clustered around the mean.

This results in a less spread out (narrower) normal distribution curve.

Explanation

Mode is the value that occurs most frequently in a dataset.

It represents the most common or popular item in the data.

Explanation

To find the range, subtract the smallest value from the largest value:

Maximum value = 28

Minimum value = 20

Range = Maximum value - Minimum value

= 28 - 20

= 8
