This prove go come out serve as the basis for query into determining the try out mean and nation mean of degree centigrade interior(a) marge customers savings account balances. The research question is do Century National Bank customers average $1500 or more in their savings accounts?

The alternative hypothesis states that Century National Bank customers have less than $1500 in their savings accounts. The numerical form of this statement is H1 < 1500. From these hypotheses we can close down that this will be a left-sided test. Step Two The take in of significance chosen is .05. This level will give us 95% confidence that our sample mean contains the tribe mean.

The seek involved is the 5% dislodge that our sample mean does not contain the population mean. Step Three The test statistics will be use to for the hypothesis will be the t-test. This is surpass because we are testing the mean s of the data from the bank and we have unkn! own variances. Such as that the population measuring rod deviation is unknown and the population is assumed common with a sample of 60. The data of the bank will be care spaciousy disassemble and them the sample information will be plugged into the look for the t-test. The t-test will be calculated by subtracting the desired standard ($1500) from the sample mean () of the accounts.
