Answer:
There is not sufficient evidence to support the claim.
Step-by-step explanation:
The claim to be tested is:
The mean respiration rate (in breaths per minute) of students in a large statistics class is less than 32.
To test this claim the hypothesis can be defined as follows:
<em>H₀</em>: The mean respiration rate of students is 32, i.e. <em>μ</em> = 32.
<em>Hₐ</em>: The mean respiration rate of students is less than 32, i.e. <em>μ</em> < 32.
The sample mean respiration rate of students is 31.3.
According to the claim the sample mean is less than 32.
The sample mean value is not unusual if the claim is true, and the sample mean value is also not unusual if the claim is false.
Thus, there is not sufficient evidence to support the claim.
Answer:
The correct option is C 20.1%.
Step-by-step explanation:
The probability distribution chart representing the opinions of employed adult women about government funding for day care is as follows:
Rating (<em>X</em>) Probability (<em>p</em>)
1 0.110
2 0.206
3 0.464
4 0.201
5 0.119
The ratings are defined as follows:
1: too little
2: helpful but not enough
3: make a difference but insufficient
4: sufficient
5: generous
The probability of women who think that the support is sufficient is, 0.201.
The percentage is: 0.201 × 100 = 20.1%
Thus, the percentage of women who think that the support is sufficient is 20.1%.
The correct option is C.
