An extrusion die is used to produce aluminum rods. Specifications are given for thelength and the diameter of the rods. For each rod, the length is classified as tooshort, too long, or OK, and the diameter is classified as too thin, too thick, or OK. Ina population of rods, the number of rods in each class is as follows:Length\DiameterToo thinокToo ThickToo short1075OK3890021Too long4255If a rod is sampled at random, what is the probability that it is either too long or toothick? Round the answer to four decimal places.

The number of rods that are too long, ntoo long=4+25+5=34 The number of rods that are too thick,…

A study was conducted to determine where zebra are found in a region containing a various habitats including savannahs, grasslands, woodlands and mountainous areas. A map of the study area was partitioned into four habitat types. The figure below shows these four habitat types. The proportion of total acreage in each of the habitat types was determined for the study area. Using an aerial survey, zebra locations were observed and classified into one of the four habitat types. The results are given in the table below. Proportion of Total Acreage Habitat Туре Number of zebra Observed Expected number of zebra 1 0.340 25 2 0.101 22 3 0.104 30 4 0.455 40 Total 1.000 117 The researchers who are conducting the study expect the number of zebra observed in a habitat type to be proportional to the amount of acreage of that type of habitat. Are the data consistent with this expectation? The critical value is 7.815 with a significance level of 0.05.
