What is the point estimate for this confidence interval?

The sample mean is 10 with a sample standard dev aton of 4, a 6.000 to 14.000 b 9.846 to 10.154 17. The 95% confidence interval for μ is 8.384 to 11.616 d 8.462 to 11.538 e None of the Above 18 The null hypothesis states that the market data indicates favorable conditions to open up your tranchise. An example of a Type I error would be A The market condition is favorable and you accepted the null hypothesis B. The market condition is favorable and you rejected the null hypothesis C. The market condition is NOT favorable and you accepted the null hypothesis D. The market condition is NOT favorable and you rejected the null hypothesis E None of the Above
