The average hole diameter of a bushing resulting from a production process is 42 mm. On average 18 out of 20 these bushing diameter values lie between 41.6 and 42.4 mm. If now 90 samples are randomly taken, each consisting of 16 bushings, and the average price of each sample of these 90 samples is depicted as points on a map with the lower and upper limits of 41.9 and 42.1 mm, respectively. Determine how many points of this imagery lie outside this boundary.

In a bag of 405 chocolate candies, 43 of them are brown. The candy company claims that 13% of its plain chocolate candies are brown. For the following, assume that the claim of 13% is true, and assume that a sample consists of 405 chocolate candies. Complete parts (a) through (e) below. a.) For the 405 chocolate candies, use the range rule of thumb to identify the limits separating numbers of brown chocolate candies that are significantly low and those that are significantly high. Values of ____ brown candies or fewer are significantly low. Values of ____ brown candies or greater are significantly high. Based on the results, is the result of 43 brown chocolate candies significantly low? Why or why not? b.) Find the probability of exactly 43 brown chocolate candies. c.) Find the probability of 43 or fewer brown chocolate candies.

The chemist responsible for a ceramics factory evaluated the presence of Cadmium in the vessels produced by the company using a standard leaching test, and the following results were obtained: [Cd] (mg/L) 0,4887 0,4758 0,5506 0,4838 0,4901 0,4954 The limit value for Cd in the leaching test is established by standard as 0.5000 mg/L. Is there evidence that the average Cadmium content in ceramics is lower than the reference value established by the standard with 95% confidence? Formulate the null and alternative hypotheses, present the critical/tabled values, calculated and complete the test in full

At an early stage of clinical trials of a certain method of gender selection, 8 couples using that method gave birth to 7 boys and 1 girl. Complete parts (a) through (e) below. a. Assuming that the method has no effect and boys and girls are equally likely, use the range rule of thumb to identify the limits separating values that are significantly low and those that are significantly high (for the number of boys in 8 births). Based on the results, is the result of 7 boys significantly high? Significantly low values for the number of girls in 8 births are ___and lower. Significantly high values for the number of girls in 8 births are ___ and higher. The result of 7 girls ____ Significantly high. (round to one decimal place as needed) b.

A data set on monthly expenditures (rounded to the nearest dollar) incurred on fast food by a sample of 500 households has a minimum value of $5 and a maximum value of $147. Suppose we want to group these data into six classes of equal widths.a. Assuming we take the lower limit of the first class as $1 and the upper limit of the sixth class as $150, write the class limits for all six classes.b. Determine the class boundaries and class widths.c. Find the class midpoints.(For the first class set the upper limit of the previous class to be 0.)
