(Round youranswer to two decimal places.) z < (c) Convert the x interval,4.0 < x < 5.5, to a z interval. (Round your answers to twodecimal places.) < z < (d) Convert the z interval, z <−1.44, to an x interval. (Round your answer to one decimal place.)x < (e) Convert the z interval, 1.28 < z, to an x interval.(Round your answer to one decimal place.) < x (f) Convert the zinterval, −2.25 < z < −1.00, to an x interval.
