Answer:

0.93 minute

Step-by-step explanation:

During the first week:

Kim ran = 1 mile

Duration for this distance = 1 minute

In the second week:

The distance covered by Kim = 1 mile

The time taken by Kim = 7% less compared to the first week

                         = 1 min - 0.07 min = 0.93 minute

<pSo, she completed 1 mile in 0.93 minute this week.

You are testing a claim that the standard deviation of time all women spend washing their hair in the morning is 15 seconds. You
AnnZ [12381]

Answer:

There is ample evidence to substantiate the assertion that the standard deviation of the duration all women take to wash their hair in the morning is 15 seconds

Step-by-step explanation:

We must first articulate the hypotheses while comprehending the statement’s context. The assertion claims that the standard deviation of time spent washing hair in the morning by all women is 15 seconds. In mathematical symbols, we express this as follows:

σ = 15

The presence of an equality sign qualifies this assertion as our null hypothesis;

H0: σ = 15

Our alternative hypothesis is the negation of the prior hypothesis;

Ha: σ ≠ 15

We learn that the preliminary outcome of the test does not reject the null hypothesis. In simple terms, this indicates that we do not reject the assertion that the standard deviation of time all women spend washing their hair in the morning is, in fact, 15 seconds, as this assertion represents our null hypothesis. A failure to reject a hypothesis during testing signifies that there is enough evidence to support it. Hence, there is enough evidence to affirm that the standard deviation of time all women spend washing their hair in the morning is 15 seconds
