Solution Steps

Solution Approach

To identify the lower class limits of a frequency distribution, we need to look at the starting value of each class interval. The lower class limit is the smallest value that can belong to a class. For the given frequency distribution, we will extract the starting value of each age range.

Step 1: Identify the Lower Class Limits

To find the lower class limits of the given frequency distribution, we examine the starting value of each class interval. The lower class limit is the smallest value that can belong to a class. For the class intervals provided, these values are extracted as follows:

  • For the interval \(10-14\), the lower class limit is \(10\).
  • For the interval \(15-19\), the lower class limit is \(15\).
  • For the interval \(20-24\), the lower class limit is \(20\).
  • For the interval \(25-29\), the lower class limit is \(25\).
  • For the interval \(30-34\), the lower class limit is \(30\).
  • For the interval \(35-39\), the lower class limit is \(35\).
  • For the interval \(40-44\), the lower class limit is \(40\).

Final Answer

The lower class limits are: \(\boxed{10, 15, 20, 25, 30, 35, 40}\).

18. Blood pressure According to a health information website, the distribution of adults' diastolic blood pressure (in millimeters of mercury, mmHg ) can be modeled by a normal distribution with mean 70 mmHg and standard deviation 20 mmHg . A diastolic pressure greater than 100 mmHg for an adult is classified as very high blood pressure. About what proportion of adults have very high blood pressure according to this criterion?

he wasn't lying. "Give me another beer," I said. Then someone called him from the back, and he drew the beer and left. I drank it slowly, hoping Brother Maceo would appear before I had finished. When he didn't I waved to Barrelhouse and left for the district. Perhaps Brother Tarp could explain; or at least tell me something about Clifton. I walked through the dark block over to Seventh and started down; things were beginning to look serious. Along the way I saw not a single sign of Brotherhood activity. In a hot side street I came upon a couple striking matches along the curb, kneeling as though looking for a lost coin, the matches flaring dimly in their faces. Then I found myself in a strangely familiar block and broke out in a sweat: I had walked almost to Mary's door, and turned now and hurried away. Barrelhouse had prepared me for the darkened windows of the district, but not, when I let myself in, to call in vain through the dark to Brother Tarp. I went to the room where he slept, but he was not there; then I went through the dark hall to my old office and threw myself into my desk chair, exhausted. Everything seemed to be slipping away from me and I could find no quick absorbing action that would get it under control. I tried to think of whom among the district committee I might call for information concerning Clifton, but here again I was balked. For if I selected one who believed that I had requested to be transferred because I hated my own people it would only complicate matters. No doubt there would be some who'd resent my return, so it was best to confront them all at once without giving any one of them the opportunity to organize any sentiment against me. It was best that I talk with Brother Tarp, whom I trusted. When he came in he could give me an idea of the state of affairs, and perhaps tell me what had actually happened to Clifton. But Brother Tarp didn't arrive. I went out and got a
