The cost of a daily newspaper varies from city to city. however, the variation among prices remains steady with a standard deviation of $0.20. a study was done to test the claim that the mean cost of a daily newspaper is $1.00. twelve costs yield a mean cost of $0.93 with a standard deviation of $0.18. do the data support the claim at the 1% level? note: if you are using a student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (in general, you must first prove that assumption, however.)
