Consider a continuous variable x that has a normal distribution with mean µ = 90 and standard deviation σ = 2. 1. The 39th percentile (P39) of the distribution is 2. The values of x that bound the middle 10% of the distribution are ■ lower border is upper border is 3. The standard z value of x = 94 is 4. The standard error (0) of the distribution of sample means of samples of size 144 is 5. If a sample of size 178 is randomly selected from the population, the probability that this sample has a average less than 88 is
