Assume the true population mean is 46.8, the t critical value is 1.76, the test statistic is 1.82, and we have (a) We have a Type II error since we rejected the null hypothesis and it is false (b) We have a correct decision since we rejected the null hypothesis and it is false (c) We have a Type I error since we rejected the null hypothesis and it is true (d) We have a correct decision since we did not reject the null hypothesis and it is true

Merrida uses a pattern in the multiplication table below to find ratios that are equivalent to 7: 9. if merrida multiplies the first term, 7, by a factor of 6, what should she do to find the other term for the equivalent ratio? multiply 9 by 1. multiply 9 by 6. multiply 9 by 7. multiply 9 by 9.

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
