Arandom sample of size n = 64 is taken from a population with mean μ = −12.2 and standard deviation σ = 5. a. calculate the expected value and the standard error for the sampling distribution of the sample mean. (negative values should be indicated by a minus sign. round "expected value" to 1 decimal place and "standard error" to 4 decimal places.)

An irrational number is a number which cannot be expressed in a ratio of two integers. In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero. While an irrational number cannot be written in a fraction.S
