Probability
For the following problem, use the 68-95-99.7 Rule to approximate the probability rather than using technology to find the values more precisely. Although controversial and the subject of some recent law suits, some human resource departments administer standard 1Q tests to all employees. One 1Q test's scores are well modeled by a Normal model with mean 100 and standard deviation 10. If the applicant pool is well modeled by this distribution, a randomly selected applicant would have what probability of scoring in the following regions? a) 120 or above c) Between 90 and 110 b) Above 100 d) Below 70 a) The probability is 0.025. (Type an integer or a decimal. Do not round.) b) The probability is 50 (Type an integer or a decimal, Do not round.) c) The probability is (Type an integer or a decimal. Do not round.) d) The probability is (0.025 (Type an integer or a decimal. Do not round.) Photo PDF doc Informat Crastad

Answer all part please sir please

For the following problem, use the 68-95-99.7 Rule to approximate the probability rather than using technology to find the values more precisely. Although controversial and the subject of some recent law suits, some human resource departments administer standard IQ tests to all employees. One 1Q test's scores are well modeled by a Normal model with mean 100 and standard deviation 10. If the applicant pool is well modeled by this distribution, a randomly selected applicant would have what probability of scoring in the following regions? a) 120 or above c) Between 90 and 110 b) Above 100 d) Below 70 a) The probability is 0.025 (Type an integer or a decimal.
