Answer:
not rejecting the null hypothesis when it is false.
Step-by-step explanation:
Significance level or alpha level is the probability of rejecting the null hypothesis when null hypothesis is true. It is considered as a probability of making a wrong decision. It is a statistical test which determines probability of type I error. If the obtained probability is equal of less than critical probability value then reject the null hypothesis.
2/3 as many tables as chairs means 3/2 as many chairs as tables. So you can make the equation 4t-95=(3/2)t. Solving for t, the amount of tables, gets you 38 and there were originally 4 times that amount of chairs in the hall so there must have been 152 chairs at first.
