Answer:
a) P(X≥143)=0
b) This contradicts the study as getting a sample with this proportion is almost impossible (if the proportion of 68% is true).
Step-by-step explanation:
If we use the normal approximation to the binomial distribution we have the following parameters (mean and standard deviation):
Then, we can calculate the probability of X being equal or more than 143 using the z-score:
This contradicts the study as getting a sample with this proportion is almost impossible (if the proportion of 68% is true).
Answer:
This statement if FALSE
Step-by-step explanation:
This question deals with the concept of competing products and how the price of a product effects its demand
There are two competing bulbs
a) Compact fluorescent light bulbs
b) Incandescent light bulbs
The first statement exclaims that the price of the product (a) decreases and this causes the demand of product (a) to increase, this would decrease the demand of product (b) as they are competitors.
To retaliate against the loss of sales of product (b) the price of product (b) is decreased, this should increase the demand of product (b) but the statement says the the demand of product (b) further decreases.
Since we know from the statement that sales were primarily driven by the price of the products, the demand of product (b) should have increased. Hence this statement is false
