Craig and Danny are planning to tr y out for the basketball team and one of the criteria fro the selection is based on free thro

erastova [34]

Answer:

It is more likely that Danny will make three free throw shots in a row.

Step-by-step explanation:

The probabilities of Craig and Danny making the throw they attempt, is given as:

Probability that Craig will make the throw = 55% = 0.55

Probability that Danny will make the throw = 71% = 0.71

Now, the probabilities that they will miss the throw can be found out by subtracting the probabilities, that they can make the throw, from 1.

Probability that Craig will miss the throw = 1 - 0.55 = 0.45

Probability that Danny will miss the throw = 1 - 0.71 = 029

Now,

Probability that Craig will miss two throws in a row = (0.45)(0.45) Probability that Craig will miss two throws in a row = 0.2025

And,

Probability that Danny will make three throws in a row = (0.71)(0.71)(0.71)

Probability that Danny will make three throws in a row = 0.3579

Since, the probability of Danny making three throws in a row is higher than the probability of Craig missing two throws in a row.

<u>Thus, it is clear that, it is more likely that Danny will make three free throw shots in a row.</u>

How many times greater is one hour then one miuntes

dezoksy [38]

There are 60 minutes in 1 hour

60 minutes - 1 minute = 59 minutes

One hour is 59 minutes greater than 1 minute.

Hope this helps. :)

A team averaging 110 points is likely to do very well during the regular season. The coach of your team has hypothesized that yo

aev [14]

Answer:

1. M=108

2. μ=110

3. In the explanation.

4. Test statistic t = -1.05

5. P-value = 0.1597

Step-by-step explanation:

The question is incomplete: to solve this problem, we need the sample information: size, mean and standard deviation.

We will assume a sample size of 10 matches, a sample mean of 108 points and a sample standard deviation of 6 points.

1. The mean points is the sample points and has a value of 108 points.

2. The null hypothesis is H0: μ=110, meaning that the mean score is not significantly less from 110 points.

3. This is a hypothesis test for the population mean.

The claim is that the mean score is significantly less than 110.

Then, the null and alternative hypothesis are:

$H_0: \mu=110\\\\H_a:\mu< 110$

The significance level is 0.05.

The sample has a size n=10.

The sample mean is M=108.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=6.

The estimated standard error of the mean is computed using the formula:

$s_M=\dfrac{s}{\sqrt{n}}=\dfrac{6}{\sqrt{10}}=1.9$

4. Then, we can calculate the t-statistic as:

$t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{108-110}{1.9}=\dfrac{-2}{1.9}=-1.05$

The degrees of freedom for this sample size are:

$df=n-1=10-1=9$

5. This test is a left-tailed test, with 9 degrees of freedom and t=-1.05, so the P-value for this test is calculated as (using a t-table):

$\text{P-value}=P(t$

As the P-value (0.1597) is bigger than the significance level (0.05), the effect is not significant.

The null hypothesis failed to be rejected.

There is not enough evidence to support the claim that the mean score is significantly less than 110.
