Explanation

When a die is rolled, the probability of getting a 5 on one roll is  1/6 because there is one 5 on the die out of 6 possible outcomes.

Since the die is rolled twice, and the rolls are independent, the probability of getting a 5 both times is:

Explanation

The coefficient of variation (CV) is the ratio of Standard deviation and Mean.

CV = (σ / μ) × 100, where σ is the standard deviation and μ is the mean.

Explanation

Let apple = x, orange = y

5x + 4y = 340

Try options:

B) 5×40 + 4×20 = 200 + 80 = 340 

Explanation

A.M. = ((x - 3) + (x + 5))/2

= (2x + 2)/2

= x + 1

Explanation

Using SPSS (Statistical Package for the Social Sciences) or other statistical software offers several advantages over calculating statistics by hand:

• Reduces errors: SPSS minimizes the chance of making errors in calculations, as it performs computations accurately and efficiently.
• Time-saving: SPSS can process large datasets and perform complex analyses much faster than manual calculations.
• Recognized software: Many researchers and organizations use SPSS, making it a widely recognized and accepted software package in the field of statistics and research.
• Transferable skill: Knowing how to use SPSS equips you with a valuable and transferable skill, beneficial for future research, academic, or professional endeavors.

Explanation

The geometric mean between 4 and 16 is √(4 × 16) = √64 = 8.

Explanation

The probability of the occurrence of an event lies between 0 and 1.

Explanation

The probability that a randomly selected family from the 400 families owns the house, given that 300 of them own houses, is: 0.75.

Explanation

• To find the mean of a set of numbers, you add up all the numbers and then divide by the total count of numbers.
• For the scores 1, 2, 3, 4, 5:
• (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3
• So, the mean of the scores is 3.

Explanation

Probability refers to the likelihood of a single event or outcome occurring, not a collection of experiments.
