Suppose that average rates of return in the stock market are normally distributed with an unknown population mean and standard deviation. If a random sample of 18 stock market investors is taken to estimate the mean average rate of return, use Excel to calculate the t-score that should be used to find a 99% confidence interval estimate for the population mean. Round your answer to three decimal places.

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
