The mean number of characters in the subject line for lecturer's emails is 38.7. 47.7% of lecturer's emails have at least one question mark in the message. A random sample of emails was taken from the Linguist List email data to investigate these claims. Load the sample data into iNZight Lite using this link and use the Summary and VIT tab to answer the following questions. The sample size is A mean of 38.7 (enter is or is not) one of the plausible values provided by a VIT bootstrap confidence interval for the mean number of characters in the subject line. Therefore, the claim about the mean number of characters in the subject line for emails (enter is or is not) supported by a VIT bootstrap confidence interval for the mean number of characters in the subject line. A proportion of 47.7% (enter is or is not) one of the plausible values provided by a VIT bootstrap confidence interval for the proportion of emails that have at least one question mark in the message. Therefore, the claim about the proportion of emails that have at least one question mark in the message (enter is or is not) supported by a VIT bootstrap confidence interval for the proportion of emails that have at least one question mark in the message. The population referred to in the claim (enter is or is not) same as the population the sample was taken from. the
