Of the 105 individualssampled from ethnicity 2, the mean life span was 44.9 years with a standard deviation of 11.4 years.Conduct a hypothesis test with a 10% level of significance to see if the mean life spans in Louisianawere the same for the two ethnicities.Step 1: State the null and alternative hypotheses.Ho: H1 – H2= VHa: µ1 - 2 vv test.)(So we will be performing a two-tailedPart 2 of 4Step 2: Assuming the null hypothesis is true, determine the features of the distribution of thedifferences of sample means.with distribution meanThe differences of sample means are t-distributedand distribution standard deviationQuestion Help: D Post to forum
