To test Ho: p= 100 versus H₂ uz 100, a simple random sample size of n=21 is obtained from a population that is known to be normally distributed. Answer parts (a)(d) Click here to view the t-Distribution Area in Right Tail. (a) If x=105 and s=9.8, compute the test statistic. t= 2.338 (Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the a=0.01 level of significance, determine the critical values. The critical values are (Use a comma to separate answers as needed.

Hey! I really need help with this question... I'm not very good at math and this would help a ton!  The school is installing whiteboards in 5 classrooms. Whiteboards, including their borders, are 6 feet wide by 10 feet long. The borders, which are 0.5 ft wide, will not be varnished.  The whiteboards can be varnished to resist stains for 40 cents per square foot or can be varnished to avoid glare from ceiling lights for 25 cents per square foot. If each room gets one whiteboard, how much more expensive will it be to varnish the whiteboards for stains than to varnish them for glare?   It will be $_________  more expensive.
