Question

hi how do you get the t value in the cal ti83

Test the indicated claim about the means of two populations. Assume that the two samples are independent and that they have been randomly selected. 3) Two types of flares are tested for their burning times (in minutes) and sample results are 3 given below. Brand X n35 x=19.4 $ 1.4 Brand Y n = 40 x 15.1 S0.8 Refer to the sample data to test the claim that the two populations have equal treans 0.05 significance level. 1) claim M, = M₂ - CA se lor2 2) Ho: M. = Me 3) Hi Moz M₂ "Two tail 4) t = -0022 Dr: 39 9 оо 10.025 -2.032 . 2.032 c) fail to reglect Hoi case 2 Not Surhicient evident to support the C m MEME 4) A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure by following a particular diet.
