The following experiment was run to determine whether or not different flavors of ben and jerry's ice cream melt at different speeds. two flavors (a and b) of ice cream were stored in the same freezer in similar-sized containers. for each observation, one teaspoonful of ice cream was taken from the freezer, transferred to a plate, and the melting time at room temperature was observed to the nearest second. nine observations were taken on each flavour, provided in the table below. flavour time in seconds a 1009 987 955 1074 994 1040 1037 999 1013 820 970 980 872 975 1061 963 857 1006 a (2 calculate the difference (d) and sample standard deviation difference (sa of the time it takes for the ice cream to m b) (2 points) state the appropriate null and alternative hypothesis to test whether there is a difference in the time it takes for the ice cream to melt. value (5 percent level of si d) (2 points) is there a significant difference in melting times at a level of significance or 5%? be sure to restate your critical value and an appropriate conclusion.
