a.
H0: =35 cars per minute
HA: 35 cars per minute
(where, =Population mean of noontime traffic flow rate).
It is a Two-Tailed test.
b.
H0: $75
HA: < $75
(where, =Population mean cost of repairing a phone screen).
It is a Left-Tailed test.
c.
H0: < 20,000
HA: 20,000
(where, =Population mean daily attendance of the park).
It is a Right-Tailed test.
d.
H0: 8 hours
HA: > 8 hours
(where, =Population mean life of the battery).
It is a Right-Tailed test.
e.
Proportion =100,000/100,000 =100% =1
H0: P =1
HA: P 1
(where, P =Population proportion of the number of responses to the survey mailed to 100,000 U.S. residents).
It is a Two-Tailed test.

For the following hypothesis test, determine the null and alternative hypotheses. Also, classify the hypothesis test as two tailed, left tailed, or right tailed The mean local monthly bill for cell phone users in this country was $43.56 in 2001. A hypothesis test is to be performed to determine whether last year's mean local monthly bill for cell phone users has decreased from the 2001 mean of $43.56 Choose the correct null and alternative hypotheses below OA. Ho : μ...
Given H0: μ1 = μ2 and Ha: μ1 ≠ μ2, determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Group of answer choices right-tailed left-tailed two-tailed
State Ho and Ha in words and in symbols. Then determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Explain your reasoning. Sketch a normal sampling distribution and shade the area for the P-value. A report claims that lung cancer accounts for at most 28% of all cancer diagnoses. State the null hypothesis in words and in symbols. The null hypothesis expressed in words is the proportion of cancer diagnoses attributable to lung cancer The null hypothesis is expressed...

Please determine for each of the following whether you REJECT H0 or DO NOT REJECT H0. a. The tails for a two-tailed hypothesis test for the mean are defined by values z = ± 1.69. The test value is z = –1.83. b. The test statistic for a right-tailed hypothesis test for the mean with 99% confidence is z = 1.45. c. The test statistic for a two-tailed hypothesis test for the standard deviation is χ2 = 6.32. The sample...
