Acharacteristic of all confidence intervals is that: a. a confidence interval always includes the population parameter. b. a confidence interval always increases in width as the sample size is increased. c. a confidence interval cannot include a value of 0. d. a confidence interval always increases in width as the level of confidence increases.

B. a confidence interval always increases in width as the sample size is increased.

Explanation:

Confidence interval is a statistical term used to describe a population growth parameter, which is unknown to the researcher. This interval represents a situation that can be calculated and that can present itself in different ways between one sample and the other, in relation to the existence of observable factors or not, proving to be reliable or not.

In summary, we can say that for this interval to be considered efficient, it is necessary that it always increase in width as the level of confidence increases.

horror and alarm

this is shown in the exserp then he beat at the door and called, but none responded, and for wrath he could have dashed the door down, but it was too stout, and he had no weapon; for his arms had been taken from him.when it was dark, suddenly it seemed to sir lancelot that the room smelled foul, as if he had been carried into the midst of the quaking marsh, and was sunk deep in the slime and weeds of a pool. then, through the arrow-slit, he saw many strange lights come, dim and blue like the wild lights that dance and flit over the lonely marshes by night; but that which made him   marvel was that these lights were two together, as if they were the eyes of evil things. and they came up to him with a breath that was cold and dank, and they seemed to peer into his face, but he could see naught of their bodies. the hair upon his head rose, and his skin went cold. they pressed all about him, and to defend himself he struck at the eyes, but his blows beat only the air. then suddenly sir lancelot felt sharp pains, as if small keen knives had been thrust into his flesh at many places. the stabs increased in number and in pain, and sir lancelot beat about himself and ran to and fro in the narrow chamber to escape   the evil eyes and the stabs, but it was in vain, and thus all night in much misery he suffered. when for sheer weariness he lay down and tried to close his eyes, the evil things would not let him, but ever they tore at him and stabbed him.
