1. Find the probability of 7 tomatos getting accepting in 6 stores when the mean is 5.5
\n" ); document.write( "---
\n" ); document.write( "Mean of what? Do you have a standard deviation?
\n" ); document.write( "--------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2.Random sample of 120 customers’s spent an average of 9.2 hours on their professional job with a sample standard deviation of 5.1 hours. Calculate the specification hours with confidence of 95%.
\n" ); document.write( "---------------
\n" ); document.write( "x-bar = 9.2 hrs
\n" ); document.write( "E = 1.96*(5.1/sqrt(120)) = 0.9125
\n" ); document.write( "----
\n" ); document.write( "95% CI: 9.2 - 0.9125 < u < 9.2 + 0.9125
\n" ); document.write( "========================================
\n" ); document.write( "
\n" ); document.write( "3.In a set of 10 samples of bike, the mileage were listed as follows
\n" ); document.write( "41, 42, 45, 42, 47, 59, 55, 60, 40, 35
\n" ); document.write( "What percent of samples are getting more than an average of 40 ?
\n" ); document.write( "---------
\n" ); document.write( "# above 40 = 8
\n" ); document.write( "Total number = 10
\n" ); document.write( "-----------------------
\n" ); document.write( "Percentage = 8/10 = 80%
\n" ); document.write( "=============================
