Suppose that we compute a 90% z confidence interval for an unknown population mean μ, which of the following is a correcet interpretation? 。the probability that μ is in this interval is 90%. 90% of all possible z confidence intervals computed from samples of the same size would contain μ. 。the probability that μ is in this interval is 10%.

The probability that μ is in this interval is 90%.

Step-by-step explanation:

If  we compute a 90% z confidence interval for an unknown population mean μ, then the correct interpretation would be :

A person can be 90% sure that the μ lies in it.

i.e. The probability that μ is in this interval is 90%.

Hence, the correct answer is "The probability that μ is in this interval is 90%."

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
