Company A makes a large shipment to Company B. Company B can reject the shipment if they can conclude that the proportion of defective items in the shipment is larger than 0.1. In a sample of 400 items from the shipment, Company B finds that 53 are defective. Conduct the appropriate hypothesis test for Company B using a 0.1 level of significance.a) What are the appropriate hypotheses?H0: p = 0.1 versus Ha: p ≠ 0.1H0: p = 0.1 versus Ha: p > 0.1 (I got this as the correct answer)H0: p = 0.1 versus Ha: p < 0.1H0: μ = 0.1 versus Ha: μ > 0.1b) What is the test statistic? Give your answer to four decimal places. -> the corret answer I got is 2.16666c) What is the critical point for the test? Give your answer to four decimal places. -> the incorrect answer I got is 1.64868d) What is the appropriate conclusion?- Fail to reject the claim that the defective proportion in the shipment is 0.1 because the test statistic is smaller than the critical point.- Conclude that the defective proportion in the shipment is greater than 0.1 because the test statistic is smaller than the critical point. - Fail to reject the claim that the defective proportion in the shipment is 0.1 because the test statistic is larger than the critical point. (This is the answer I picked and it is incorrect)- Conclude that the defective proportion in the shipment is greater than 0.1 because the test statistic is larger than the critical point.

You commute to work a distance of 40 miles and return on the same route at the end of the day. Your average rate on the return trip is 30 miles per hour faster than your average rate on the outgoing trip. If the round trip takes 2 hours, use a rational equation and factoring to find your average rate on the outgoing trip to work?

The game of clue involves 6 suspects, 6 weapons, and 9 rooms. one of each is randomly chosen and the object of the game is to guess the chosen three. (a) how many solutions are possible? in one version of the game, the selection is made and then each of the players is randomly given three of the remaining cards. let s, w, and r be, respectively, the numbers of suspects, weapons, and rooms in the set of three cards given to a specified player. also, let x denote the number of solutions that are possible after that player observes his or her three cards. (b) express x in terms of s, w, and r. (c) find e[x].

Given: AB = 12 AC = 6 Prove: C is the midpoint of AB. Proof: We are given that AB = 12 and AC = 6. Applying the segment addition property, we get AC + CB = AB. Applying the substitution property, we get 6 + CB = 12. The subtraction property can be used to find CB = 6. The symmetric property shows that 6 = AC. Since CB = 6 and 6 = AC, AC = CB by the property. So, AC ≅ CB by the definition of congruent segments. Finally, C is the midpoint of AB because it divides AB into two congruent segments.
