Answer:
growth mindset means that you believe your intelligence and talents can be developed over time. A fixed mindset means that you believe intelligence is fixed—so if you're not good at something, you might believe you'll never be good at it.
Answer:
3.59 minutes
Explanation:
We solve this question using z score formula
Using Excel
Z-SCORE= (DataPoint-AVERAGE(DataSet))/STDEV(DataSet)
IN EXCEL,
AVERAGE, an excel function that calculates the Average of data set
STDEV.S: calculates the standard deviation while treating the data as a ‘sample’ of a population.
STDEV.P: This function calculates the standard deviation while treating the data as the entire population.
Z score formula = x - μ/σ
x = ?? μ = 2.5 minutes σ = 0.5 minutes
We are asked : If 1.5% of the callers are put on hold for longer than x minutes, what is the value of x?
Hence, Longer than = Greater than =
100 - 1.5%
= 100 - 0.015
= 0.985 ( 98.5%)
Using Excel we calculate = z score for 98.5 percentile
= 2.1701
Z score = x - μ/σ
2.1701 = x - 2.5/0.5
2.1701 × 0.5 = x - 2.5
1.08505 = x - 2.5
x = 1.08505 + 2.5
x = 3.58505
Approximately to 2 decimal places = 3.59 minutes
Therefore, 1.5% of the callers are put on hold for longer than 3.59 minutes.
By simply prohibiting others from entering the markets is the best example how the government sanctions technological monopolies.
This is to avoid competitors and give the people no choice but to buy thier products
