Question

Four types of tennis shoes were evaluated in four different categories. Each category has its own mean and stdev. Each oven was scored. Analyze the chart and fill in the blanks in the chart:

MAKER	Mean for category	SCORE	STDEV	Z score
ALIF	2.09	2.01	.9	BLANK A
CONEYSAU	32.46	31	3.009	BLANK B
BOKREE	102.9	BLANK C	32	0.00
NICKEE	1036	1111	111	BLANK D

We are comparing the relative position of these scores

Answer 1

Four types of tennis shoes were evaluated in four different categories. Each category has its own mean and stdev. Each oven was scored. Analyze the chart and fill in the blanks in the chart:

MAKER	Mean for category	SCORE	STDEV	Z score
ALIF	2.09	2.01	.9	BLANK A
CONEYSAU	32.46	31	3.009	BLANK B
BOKREE	102.9	BLANK C	32	0.00
NICKEE	1036	1111	111	BLANK D

We are comparing the relative position of these scores

We know that : Z score = ( SCORE - Mean )/STDEV

For ALIF

BLANK A = ( 2.01 - 2.09 )/0.9

BLANK A = -0.08/0.9

BLANK A = -0.0889

For CONEYASU

BLANK B = ( 31 - 32.46 )/3.009

BLANK B = -1.46/3.009

BLANK B = -0.4852

For BOKREE

0.00 = ( BLANK C - 102.9 )/32

( BLANK C - 102.9 ) = 32*0

( BLANK C - 102.9 ) = 0

BLANK C = 102.9 + 0

BLANK C = 102.9

For NICKEE

BLANK D = ( 1111 - 1036 )/111

BLANK D = 75/111

BLANK D = 0.6757
