- An anagram of a word is a rearrangement of the letters of the word. (a) How many anagrams of the word LOVE are possible? (b) How many different anagrams of the word KISSES arc possible?Read measurements w-z on the enlarged fractional rule shown in Figure 30-13.If 5 and 2 are the Arithmetic Mean and Harmonic Mean of two distinct numbers, then their Geometric Mean is
- Allowing digits and special characters (as well as case-sensitive letters) creates an enormous number of passwords. However, computers can check passwords very quickly. Assume a computer can check approximately 170 million passwords per second. (Note that this is an approximate value, so it is a mistake to give answers with several decimal places that are not significant). a) How long (in minutes) would it take a computer to check every possible 5 character password? b) How long (in years) would it take a computer to check every possible 9 character password?2) Find the z-score in which 93.70% of the z-scores in a population are below that value.3) Find the z-score in which 98.46% of the z-scores in a population are above that value.4) Find the z-score in which 11.12% of the z-scores in a population are above that value.8. Suppose X ~ N(7, 1). What value of x has a z-score of −1.25? (Enter an exact number as an integer, fraction, or decimal.)x =
- Suppose you are interested in testing whether the mean earning of men is representative of the earning of the entire U.S. male population. After surveying a sample of males, you find that the average male earned $40,607 and the average male in the population earned $43,405. State the null and research hypotheses. Use the appropriate symbolic notation for each: H0: H1:This question is not on any test. The table below shows the number of people for three different race groups who were shot by police that were either armed or unarmed. These values are very close to the exact numbers. They have been changed slightly for each student to get a unique problem. Race/Armed Suspect was Armed Suspect was unarmed Total Black 543 60 603 White 1176 67 1243 Hispanic 378 38 416 Total 2097 165 2262 Give your answer as a decimal to at least three decimal places. If you compare answers d, e and f it shows the highest percentage of unarmed people being shot is most likely white. Why is that? This is because there are more white people in the United States than any other race and therefore there are likely to be more white people in the table. Since there are more white people in the table, there most likely would be more white and unarmed people shot by police than any other race. This pulls the percentage of white and unarmed up. In addition, there…1. An economist believes a certain indicator has amean greater than 73. a) Show steps NA of NATDRC for this claim. b) Suppose we find enough evidence againstthe H0 .
