Answer:
0.0139
Explanation:
Given that:
The number of sample (n) = 21
The sample distribution has mean (μ) and a standard deviation of σ/√n
The z score is given as (x - mean)/ standard deviation
x = 94.8 wpm, let us assume that σ = 10 and μ = 90
Therefore: z = (x - μ) / (σ/√n) = (94.8 - 90) / (10/√21) = 2.2
To calculate the probability using Z table:
P(X>94.8) = P(Z>94.8) = 1 - P(Z<94.8) = 1 - 0.9861 = 0.0139
The probability is low that is less than 0.05, the program is more effective than the old one.
Answer:
two part pricing
Explanation:
A Two-part tariff (TPT) is a type of price gouging in which the price of a good or service consists of 2 sections-a rub-sum of the per-unit fee. Such a selling strategy generally occurs except in part or entirely monopolistic industries. It is built to allow the company to absorb more surplus value in a non-discriminatory pricing framework than it ever has before.
Two-part tariffs in open markets can also occur when customers are unsure regarding their final requirement. Consumers of fitness centers, for instance, may be unsure regarding their degree of potential dedication to an exercise routine.
