Ninety-five percent of all marigold flowers have a height between 10.9cm and 119.0cm and their height is normally distributed what’s the mean?

mean = 64.95

Step-by-step explanation:

According to the Empirical rule , 95% of the population lies with 2 standard deviations from the mean when data is normally distributed.

Given:  95% of all marigold flowers have a height between 10.9 cm and 119.0 cm.

If height is normally distributed , then

Mean - 2 standard deviation = 10.9    (i)

Mean + 2 standard deviation = 119.0    (ii)

Add (i) and (ii), we get

2 Mean = 10.9+119.0

⇒ 2 Mean = 129.9

⇒   Mean = 64.95  [divide both sides by 2]

So, mean = 64.95

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
