Answer: 59.342
Step-by-step explanation:
The chi-square critical values are used to find the confidence interval for σ.
Left critical value = [i.e. chi-square value from chi-square table corresponding to degree of freedom n-1 and significance level of ]
To find : left critical value for 95% confidence interval for σ with n = 41.
Significance level :
degree of freedom = 41-1=40
Now, the left critical value for 95% confidence interval for σ with n = 41 is the chi-square value corresponding to degree of freedom n-1 and
=59.342 [from chi-square table ]

<h2>
<em>Theoretical Probability Definition</em></h2>
<em>Theoretical probability is the theory behind probability. To find the probability of an event using theoretical probability, it is not required to conduct an experiment. Instead of that, we should know about the situation to find the probability of an event occurring. The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes.</em>

<em>Find </em><em>the </em><em>probability of rolling a 5 on a fair </em><em>di</em><em>e</em></h3>
<em>Solution:</em><em> </em>
<em>To find the probability of getting 5 while rolling a die, an experiment is not needed. We know that there are 6 possible outcomes when rolling a die. They are 1, 2, 3, 4, 5, 6.Therefore, the probability is,Probability of Event P(E) = No. of. Favourable outcomes/ No. of. Possible outcomes.P(E) = 1/6.Hence, the probability of getting 5 while rolling a fair die is 1/6.</em>

I got 285..
5+3 = 35 (3 dime = 30, 1 nickle = 5)
2(5) = 250 ( 2 quarters = 50, 1 nickle = 5)
250+35= 285
