Question

A. Find the p-value of a 2 sided 95% confidence test of hypothesis if the value found for the sample mean was 14.53 the Null Hypothesis assumes that the population mean is Mu = 14, the population standard deviation is 3 and the sample size is 14

B. Find the p-value of a 2-sided 95% confidence test of hypothesis if the value found for the sample mean was 35.71 the Null Hypothesis assumes that the population mean is Mu = 32, the population standard deviation is 8 and the sample size is 6

C. Find the p-value of a test of hypothesis if the value found for the sample mean was 591.33 the Null Hypothesis assumes that the population mean is Mu = 538, the population standard deviation is 152 and the sample size is 13

**PLEASE SHOW WORK.**

Answer #1

A) The test statistic z = ()/()

= (14.53 - 14)/(3/)

= 0.66

P-value = 2 * P(Z > 0.66)

= 2 * (1 - P(Z < 0.66))

= 2 * (1 - 0.7454)

= 2 * 0.2546 = 0.5092

B) The test statistic z = ()/()

= (35.71 - 32)/(8/)

= 1.14

P-value = 2 * P(Z > 1.14)

= 2 * (1 - P(Z < 1.14))

= 2 * (1 - 0.8729)

= 2 * 0.1271 = 0.2542

C) The test statistic z = ()/()

= (591.33 - 538)/(152/)

= 1.27

P-value = 2 * P(Z > 1.27)

= 2 * (1 - P(Z < 1.27))

= 2 * (1 - 0.8980)

= 2 * 0.102 = 0.204

Find the P-value of a test of hypothesis if the value found
for the sample mean was 35.03 the Null Hypothesis assumes that the
population mean is Mu=33, the population standard deviation is 8
and the sample size is
sample size is 12

A. Find the value of Beta, when the Null Hypothesis assumes a
population mean of Mu = 950, with a population standard deviation
of 180, the sample size is 4 and the true mean is 1087.87 with
confidence interval of 95%
B. Find the value of Beta, when the Null Hypothesis assumes a
population mean of Mu = 900, with a population standard deviation
of 277, the sample size is 7 and the true mean is 1202.94 with
confidence interval...

Using either the critical value rule or the p-value
rule, if a one-sided null hypothesis for a single mean cannot be
rejected at a given significance level, then the corresponding
two-sided null hypothesis (i.e., the same sample size, the same
standard deviation, and the same mean) will ______________ be
rejected at the same significance level.

sometimes
never

test described below
the claim is that for a smartphone carrier's data speed at
airports, the mean is mu =19.00 mbps. the sample size n = 14 and
the test statistic is t= 1.118.
