IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. A sample of 10 children in a gifted learner program are found to have a mean IQ of 106. Use a z-test to determine if this is significantly different from the normal population mean. What are your specific null and alternative hypothesis? Z=+ - 1.96 standard deviation m= 4.743 Z= 1.26 Will you reject or retain the null hypothesis? We will retain the null...
