Answer:

P( green or blue) = 9/20

P( green, yellow or blue)  = 3/4

P( green,  red or blue)  = 7/10

Step-by-step explanation:

There are 40 slips in all, Green: 15, Red: 10, Blue: 3, Yellow: 12.

P( green or blue) = green or blue / total

                            = (15 + 3)/ 40

                            = 18/40

                             = 9/20

P( green, yellow or blue) = green yellow or blue / total

                            = (15+12 + 3)/ 40

                            = 30/40

                             = 3/4

P( green, red or blue) = green  red or blue / total

                            = (15+10 + 3)/ 40

                            = 28/40

                             = 7/10

A national dental association conducted a survey to find the average (mean) amount of time dentists spend on dental fillings per
eduard

Answer:

The probability of finding a sample mean less than 18 hours is 0.0082

Step-by-step explanation:

To find the probability of finding a sample mean less than 18 hours, we need to calculate the z-score of this sample mean 18. And the probability of finding a sample mean less than 18 hours is P(z<z(18)).

Z-score can be calculated as follows:

z(18)=\frac{X-M}{\frac{s}{\sqrt{N} } } where

  • X is the sample mean (18 hours)
  • M is the average hours dentists spend per week on fillings (20 hours)
  • s is the standard deviation (10 hours)
  • N is the sample size (144)

Putting the numbers, we get:

z(18)=\frac{18-20}{\frac{10}{\sqrt{144} } }=-2.4

Using z- table we can find that P(z<z(18)) = 0.0082
