A bag of 100 tulip bulbs purchased from a nursery contains 20 red tulip​ bulbs, 20 yellow tulip​ bulbs, and 60 purple tulip bulb
nadezda [96]

Answer: a) 0.2   b) 0.6

c) The event of selecting red tulip is not likely to occur.

The event of selecting purple tulip is likely to occur.

Step-by-step explanation:

Given : Total number of tulips = 100

The number of red tulips = 20

The number of purple tulips =60

The probability that a randomly selected tulip bulb is​ red :-

\dfrac{\text{Number of red tulips}}{\text{Total tulips}}\\\\=\dfrac{20}{100}=0.2

Since 0.2 is less than 0.5.

It means that the event of selecting red tulip is not likely to occur.

The probability that a randomly selected tulip bulb is​ purple :-

\dfrac{\text{Number of purple tulips}}{\text{Total tulips}}\\\\=\dfrac{60}{100}=0.6

Since 0.6 is more than 0.5.

It means that the event of selecting purple tulip is likely to occur.

The compressive strength of concrete is being tested by a civil engineer who tests 12 specimens and finds that the sample mean i
ki77a [65]

Answer:

The 95% confidence interval for mean compressive strength is:

3237.3\leq \mu\leq 3282.5

Step-by-step explanation:

We have a sample of n=12 specimens, with sample mean=3259.9 and sample standard deviation = 35.57.

We know the population is normally distributed.

For a 95% confidence interval and df=n-1=11, the t-statistic is t=2.201.

Then, the CI can be expressed as:

M-t*s/\sqrt{N}\leq \mu\leq M+t*s/\sqrt{N}\\\\3259.9-2.201*35.57/\sqrt{12}\leq \mu\leq 3259.9+2.201*35.57/\sqrt{12}\\\\ 3259.9-22.6\leq \mu\leq 3259.9+22.6\\\\3237.3\leq \mu\leq 3282.5
