A manufacturing company produces electrical insulators. If the insulators break when in use, a short circuit is likely to occur. To test the strength of the insulators, destructive testing is carried out to determine how much force is required to break the insulators. Force is measured by observing the number of pounds of force applied to the insulator before it breaks. The following data (stored in force) are from 30 insulators subjected to this testing1,870 1,728 1,656 1,610 1,634 1,784 1,522 1,696 1,592 1,6621,866 1,764 1,734 1,662 1,734 1,774 1,550 1,756 1,762 1,8661,820 1,744 1,788 1,688 1,810 1,752 1,680 1,810 1,652 1,736a. At the 0.05 level of significance, is there evidence that the population mean force is greater than 1,500 pounds?b. What assumption about the population distribution is needed in order to conduct the �t test� in (a)?c. Construct a histogram, boxplot or normal probability plot to evaluate the assumption made in (b).d. Do youthink that the assumption needed in order to conduct the t test is 9a0 is valid? explain

Iam stuck on one problem. my mind is in absoloute vacation mode. i literallty just need to finish this to be done will give brainliest and all my points if i have to! 1- point free throw and 2- point feild goal. he made 35 shots, and scored 62 points how many of each shot did he make in 1 minute? (i already did the math. he made 8 1-point free throws and 27 2-point feild goals.) 1. write two equations for the problem. (i had a major brain fart.)

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142
