A typical of 1 pack is delivered off a specialist in 1 second. The laborer, of course, prepares a report using the 5 packs got. The time between bundles is shown as a remarkable self-assertive variable. Let X be a subjective variable conveying the time it takes the specialist to set up a document. The time taken to establish up a standard;

a) Find the probability that it is more than 10 seconds.

b) Find the probability that it is between 5 seconds and 10 seconds.

Is the public wrongdoing rate genuinely going down? A couple of sociologists say yes! They say that the legitimization the decline in wrongdoing rates during the 1980s and 1990s is economics. It gives off an impression of being that the general population is developing, and more prepared people do less bad behaviors. According to the FBI and the Justice Department, 70% of all catches are of folks developed 15 to 34 years.? Suppose you are a humanist in Rock Springs, Wyoming, and a sporadic illustration of police records showed that of 34 catches per month prior, 21 were of folks developed 15 to 34 years. Use a 1% level of significance to test the case that the general population degree of such catches is the city interesting comparable to 70%. Tackle the issue using both the standard system and the P-regard method. Since the assessing movement of p? is the common assignment, you can use fundamental characteristics from the standard run of the mill flow as exhibited in the table of essential potential gains of the z scattering. (Round the test estimation and the essential worth to two decimal spots. Round the P-worth to four decimal spots.)
