A packaging device is set to fill detergent power packets with a mean weight of 5 Kg. The standard deviation is known to be 0.01 Kg. These are known to drift upwards over a period of time due to machine fault, which is not tolerable. A random sample of 100 packets is taken and weighed. This sample has a mean weight of 5.03 Kg and a standard deviation of 0.21 Kg. Can we calculate that the mean weight produced by the machine has increased? Use 5% level of significance.
a random sample of 100 doctors was selected. Suppose you reject the null hypothesis. What conclusion can you draw?
Find the average cost of a loaf of bread in your area and compute the cost per day for one year. (Remember that average is the mean, median, mode, and midrange, but choose the best for the data.) 1. What measures of central tendency did you use?
In the order of operations Pemdas requires that exponentation takes precedence over multiplication, so we cannot multiply 4*2 without first evaluating 2^x, but we could divide both sides by 4.
The manufacturer of the X-15 steel-belted radial truck tire claims that the mean mileage the tire can be driven before the tread wears out is 60,000 miles. The standard deviation of the mileage is 5,000 miles.
The standard deviation of 6. What is the probability that a class of 50 has an average midterm mark that is less than 75?
Find the 95% confidence interval for the true population mean. Identify the point estimate for mean and margin of error.
