6.1 Given a standardized normal distribution (with a mean of 0 and a standard deviation of 1‚ as in Table E.2)‚ what is the probability that a. Z is less than 1.57? b. Z is greater than 1.84? c. Z is between 1.57 and 1.84? d. Z is less than 1.57 or greater than 1.84? 6.5 Given a normal distribution m = 100 and s = 10 what is the probability that a. X > 75? b. X < 70? c. X < 80 or X > 100? d. Between what two X values (symmetrically distributed around the mean)

changes for remaining life time ascending. 0• In this scheduling policy bundles are sorted taking into account their remaining time-to-live (TTL). Bundles with a longer remaining TTL are scheduled to be sent first because they have a higher probability to reach its final destination. Both FIFO and Random scheduling policies do not take into account the time-to live(TTL) of bundles. TTL is a timeout value that expresses the amount of time that bundles should be stored before being discarded

SHANNON T I NTRODUCTION HE recent development of various methods of modulation such as PCM and PPM which exchange bandwidth for signal-to-noise ratio has intensified the interest in a general theory of communication. A basis for such a theory is contained in the important papers of Nyquist 1 and Hartley2 on this subject

1. Use the sales forecaster’s predication to describe a normal probability distribution that can be used to approximate the demand distribution. Sketch the distribution and show its mean and standard deviation. Let’s assume that the expected sales distribution is normally distributed‚ with a mean of 20‚000‚ and 95% falling within 10‚000 and 20‚000. We know that +/- 1.96 standard deviations from the mean will contain 95% of the values. So‚ we can get the standard deviation by: z = (x -

However‚ others assume that probability or coincidence can explain this anomalous experience. Explain why some people see dreams which later come true as evidence for the paranormal‚ whereas other people do not. Use your knowledge of probability judgments and/or coincidence in your answer.

attributes that increment the probability that the document belongs to a class‚ are included in the classification model.\looseness=-1 The LSPTAN heuristic initially builds the model based on Naive Bayes and initializes a set of orphans $O$‚ inserting into $O$ all the terms of the vocabulary. Then‚ for each test document‚ the technique evaluates each term as a Super Parent ($a_{sp}$) and‚ at the end‚ it selects as $a_{sp}$ the term that has the highest probability $P(c_i | d_t‚ a_{sp})$.
