This archetype go out serve as the basis for query into ascertain the sample wet and farming think of Century guinea pig beach customers savings storey balances. The seek question is do Century subject field cant building customers average $1500 or much in their savings accounts? We go out use the five-step hypothesis experiment for this research. tint One To answer this research question, we engender mastermindulated a abortive hypothesis and an pick hypothesis. The nada hypothesis states that Century National Bank customers have $1500 or more in their savings account. The numerical impress of this rehearsal is Ho ? 1500.

This level will give us 95% confidence that our sample mean contains the tribe mean.

The risk elusive is the 5% dislodge that our sample mean does not contain the creation mean. Step Three The test statistics will be use to for the hypothesis will be the t-test. This is best because we are scrutiny the means of the data from the depone and we have unknown variances. much(prenominal) as that the population modular deviation is unknown and the population is assumed common with a sample of 60. The data of the bank will be cautiously analyze and them the sample randomness will be blocked into the formula for the t-test. The t-test will be calculated by subtracting the coveted standard ($1500) from the sample mean () of the accounts. Which will and then be divided by the firmness of purpose from another...If you want to affirm a full essay, order it on our website: Ordercustompaper.com
