Snowcat [4.5K]3 years ago
8 0

Answer:

a is 7/25

b is 14/25

c is 24

Step-by-step explanation:

a) because there are 25 possible outcomes and 7 of them are 3 it is 7/25

b) using the same logic 14 possible outcomes are even

c) because the probability of it being 2 is 3/25, which can be made into ?/200 by multiplying the 25 by 8, which means we have to do the same to the 3, making it 24

uppose germination periods, in days, for grass seed are normally distributed and have a known population standard deviation of 2
natka813 [3]

Answer: 0.701

Step-by-step explanation:

Formula :  EBM =z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}} , where \alpha= significance level , \sigma = Population standard deviation, n= sample size.

As per given,  n= 22

\sigma = 2

Critical z- value for 90% confidence level : z_{\alpha/2}=1.645

Then,

 EBM =(1.645)\dfrac{2}{\sqrt{22}}\\\\=(1.645)\dfrac{2}{4.690416}\\\\\approx0.701

Hence ,  error bound (EBM) of the confidence interval with a 90% confidence level= ± 0.701
