According to a Niclsen survey, 92% of consumers around the world say that they trust recommendations from

friends and family most, above all other forms of advertising. Suppose we took random samples of n = 100

consumers from this population and computed the proportion of consumers in each sample who trust

recommendations from friends and family most.

What will be the shape of the sampling distribution of the proportions of consumers who trust

recommendations from friends and family most?

Choose 1 answer:

Skewed to the left

©

Skewed to the right

Approximately normal

Uniform

Answer:

what grade?

Step-by-step explanation:

The shape of the sampling distribution of the proportions of consumers will be skewed to the left. Hence, option A is correct.

Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.

As per the given information in the question,

Proportion = 92% = 0.92

Sample size, n = 100

As,

np = (100)(0.92) = 92

Use the equation given below,

n(1 - p)

= 100(1 - 0.92)

= 100 - 92

= 8

n(1 - p) = r < 10

When sampling distribution have fewer than 10 expected failure per sample, distribution of sample is left skewed.
