Assuming that the model is correctly specified, test, at the 1% significance level, the null hypothesis that, all else being equal, the number of members in a household does not affect expenditures on vacation travel against the alternative that the greater the number of household members, the lower the vacation travel expenditures. This is a hypothesis test for the regression coefficients. Part 13 The null and alternative hypotheses are shown below.

A janitor at a large office building believes that his supply of light bulbs has a defect rate that is different than the defect rate stated by the manufacturer. The janitor's null hypothesis is that the supply of light bulbs has a defect rate of p - 0.09 (the light bulb manufacturer's stated defect rate). Suppose we do a hypothesis test with a significance level of 0.01. Symbolically, the null and alternative hypothesis are as follows: Ho: p = 0.09 and Ha:p > 0.09. The janitor calculates a p-value for the hypothesis test of approximately 0.113. Choose the correct interpretation for the p-value. O The p-value tells us that the true population rate of defective light buibs is approximately 0.113. O The p-value tells us that the probability of concluding that the defect rate is equal to 0.09, when in fact it is greater than 0.09, is approximately 0.113. O The p-value tells us that if the defect rate is 0.113, then the probability that…arrow_forward
