Is it appropriate to use the Student's t statistic to construct a 95% confidence interval for the mean shade of Mezza Perla tile? If so, construct the confidence interval. If not, explain why not.
The article “An Automatic Visual System for Marble Tile Classification describes a measure for the shade of marble tile in which the amount of light reflected by the tile is measured on a scale of 0-255. A perfectly black tile would reflect no light and measure 0, and a perfectly white tile would measure 255. A sample of nine Mezza Perla tiles were measured, with the following results:
204.999 206.149 202.102 207.048 203.496
206.343 203.496 206.676 205.831
Yes it is appropriate, since there are no outliers.

Matched processors for two orthogonal signals for multiple access.
The following worksheet specifies a pair of 10-sample CDMA orthogonal data signals: sA sub "1" in B5:B14 and sB sub "1" in C5:C14. Random transmitted bits DA sub "t" and DB sub "t" are computed in B1 and D1. The transmitted signal sAT sub "i" (in D5:D14) = sA "sub "i" if DAt=1 and =-sA sub "i" if DAt=0. The transmitted signal sBTi (in E5:E14) = sBi if DBt=1 and =-sBi if DBt=0. The Gaussian noise sequence Ni SD ? sub "N" is specified in F1. The detected signal X sub "i" is computed in G5:G14. The matched processor component sAiX sub "i" is computed in H5:H14 and VA is computed in H16. The detected bit DAr is computed in B2 from VA. The matched processor component sB sub "i" X sub "i" is computed in I5:I14 and VB is computed in I16. The detected bit DB sub "r" is computed in D2 from VB.
