Suppose the number of free throws in a basketball game by one player are normally distributed with a standard deviation 0.97 free throws. a random sample of basketball players from the population produces a sample mean of x¯=4.9 free throws. what value of z should be used to calculate a confidence interval with a 95% confidence level? 20.10 1.282 20.05 1.645 0.025 1.960 20.005 2.576 2.326

1.960

Step-by-step explanation:

The value of z we use to calculate a confidence interval with a () confidence level is a two-tailed test value i.e. represented by :-

Given : The level of confidence:

Then, significance level :

With the help of standard normal distribution table for z , we have

Hence, the value of z should be used to calculate a confidence interval with a 95% confidence level =1.960

whats the question?
