Q-Mart is animated in comparing its courageous and fecourageous customers. Q-Mart would relish to apprehend if the total of capital late by its fecourageous carry customers differs, on mediocre, from the total late by its courageous carry customers. 

To acceptance this investigation, an analyst self-possessed chance patterns of 25 fecourageous customers and 22 courageous customers. Inveterate on these patterns, on mediocre, the 25 women carry customers late $102.23 and the 22 men carry customers late $86.46. Moreover, the pattern criterion inconsequence of the total carryd by the 25 women was $93.393, and the pattern criterion inconsequence of the total carryd by the 22 men was $59.695. 

Suppose, using a 10% raze of tokenificance, you craving to apprehend if there is satisfactory cupelimony for Q-Mart to decide that, on mediocre, the total late by women carry customers differs from the total late by men carry customers. That is imply you craving to cupel 

H0: f$mu _{W} = mu _{M}f$ versus H1: f$mu _{W}   eq mu _{M}f$

Assuming that the totals late by fecourageous and courageous carry customers at Q-Mart are naturally select, inveterate on the act advocated by Bluman, what is/are the delicate treasures that you would use to pass this cupel of fancy? Attribute your acceptance, rounded to 3 decimal attributes, in the bleak. If there are two delicate treasures, attribute solely the actual treasure in the bleak. For pattern, 2.035 would be a fairly-deduced memorandum.   [removed]

For pattern: {1+1i} is conclusive inasmuch-as {1+i} is not. {0+9i} is conclusive inasmuch-as {9i} is not. 

Scores on a mathematics scrutiny rejoinder to flourish a natural division delay moderation of 65 and criterion inconsequence of 15. The preceptor cravinges to communicate a progression of “C” to scholars scoring between the 60th and 70th percentiles on the exam. 

What charges represents the 60th percentile charges on the mathematics exam? Attribute your acceptance in the bleak, rounded to a solid sum. For pattern, 62 would be a fairly-deduced memorandum. [removed]

In a narrative systematize, scholars captivate a weekly multiple excellent taunt consisting of 6 investigations, each delay 4 potential acceptances. If a scholar chancely guesses at the acceptance to each investigation for solid taunt, then what is the moderation sum of set-right acceptances the scholar conciliate get on each taunt? 

Round your acceptance to one decimal attribute as certain. For pattern, 4.5 would be a fairly-deduced memorandum.

Let x be a chance wavering representing dividend agree of Australian bank accumulations. We may feign that x has a natural division delay f$sigma f$ = 2.8%. A chance pattern of 16 Australian bank accumulations has a pattern moderation dividend agree of 8.91%. For the solid Australian accumulation communicate, the moderation dividend agree is f$mu  f$ = 6.4%. If you wanted to cupel, at a .05 raze of tokenificance, to enumerate if these axioms designate that the dividend agree of all Australian bank accumulations is loftier than 6.4% what is the delicate treasure that you would use? Attribute your acceptance, rounded to 2 decimal attributes, in the bleak. For pattern, 2.34 would be a fairly-deduced memorandum. [removed]
