7. As part of a class project, the teacher brings to class a candy jar full of gumballs of two different colors, red and green. The assignment is to estimate the proportion of red gumballs in the jar. Suppose that after the jar is shaken well, one of the students draws 25 gumballs from the jar: 19 are red and 6 are green. Suppose that the jar contains 40 red gumballs and 160 green gumballs, Complete parts (a) through (c) below. (a) Give the parameter for the percentage of red gumballs in the jar. %. (Type an integer or a decimal.) (b) Give the sampling error, expressed as a percent. %. (Type an integer or a decimal.) (c) Is the sampling error found in (b) a result of sampling variability or of sampling bias? Explain. O A. The error was caused by sampling variability. Simple random sampling, which suffers from selection bias, was used. O B. The error was caused by sampling bias. Simple random sampling, which does not suffer from selection bias, was used. O C. The error was caused by sampling bias. Simple random sampling, which suffers from selection bias, was used. O D. The error was caused by sampling variability. Simple random sampling, which does not suffer from selection blas, was used
