Compute p(x) using the binomial probability formula. then detemine whether the normal distribution can be used to estimate this probability. if so, approximate p(x) using the normal distribution and compare the result with the exact probability. n= 44 p= 0.4 x=23, use the binomial probability formula to find p(x) round to four decimal places as needed2. why can the normal distrubution be used to approximate this probability a. because np(1-p) %u2265 10 b. because np(1-p) %u2264 10 c. because %u221anp(1-p) %u2265 10 d because %u221anp(1-p) %u2264 10approximate p(x) using the normal distribution. use the standard normal distribution table3. p(x)= . by how much do the exact and approximate probabilities contracting a normal probability plot, what does fi representa. the value of fi represents the expected number of observation less than or equal to the ith data valueb. the value of fi represents the expectedz-score of the ith data valuec. the value of fi represents the expected proportion of observation less than or equal to the ith data value
