In a study, researchers wanted to measure the effect of alcohol on the hippocampal region, the portion of the brain responsible for long-term memory storage, in adolescents. the researchers randomly selected 11 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm cubed. an analysis of the sample data revealed that the hippocampal volume is approximately normal with x overbarequals8.14 cm cubed and sequals0.7 cm cubed. conduct the appropriate test at the alphaequals0.01 level of significance. state the null and alternative hypotheses. upper h 0: mu ▼ greater than less than not equals equals nothing upper h 1: mu ▼ greater than not equals equals less than nothing (type integers or decimals. do not round.) identify the t-statistic. t 0equalsnothing (round to two decimal places as needed.) identify the p-value. p-valueequalsnothing (round to three decimal places as needed.) make a conclusion regarding the hypothesis. ▼ fail to reject reject the null hypothesis. there ▼ is not is sufficient evidence to claim that the mean hippocampal volume is ▼ greater than less than equal to nothing cm cubed. enter your answer in each of the answer boxes.

Ineed asap. 35 points. in order for two polygons to be similar, two conditions must be met. first, all pairs of corresponding sides must be in proportion. second, all corresponding angles must be congruent. prove that angle congruence is not enough, by itself, to establish that two polygons are similar. do this by describing or drawing two polygons that are not similar but whose corresponding angles are all congruent.
