State whether the quantity described is a parameter or a statistic and give the correct notation. Average household income for a
kogti [31]

Answer:

b) statistic.

Step-by-step explanation:

In applied statistical work we rarely have the opportunity to measure entire populations, instead we make inferences about the populations from samples drawn, ideally randomly from the population. We usually want to know averages from whole populations, but use the average from a sample as our best guess at the population average. The unknown population average is called a parameter. The known sample average is called a statistic.

As a matter of convention, most statistical texts use greek symbols for population parameters and the English or Arabic letters for sample statistics. For example, a sample mean is often denoted as x-bar . Population means are denoted with the lower-case greek letter mu μ .

Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace t
KengaRu [80]

Answer:

0.139

Step-by-step explanation:

We are given that

Total number of cards=52

n=18

We have to find the probability of drawing at least 7 spades

Total number of spaded in deck of 52 cards=13

Probability  of getting spade=p=\frac{13}{52}=\frac{1}{4}

Probability,P(E)=\frac{favorable\;cases}{total\;number\;of\;cases}

Probability  of getting no spade=q=1-p=1-\frac{1}{4}=\frac{3}{4}

By binomial theorem of probability

P(X=x)=\binom{n}r}p^rq^{n-r}

P(x\geq 7)=1-P(x\leq 6)

The probability of drawing at least 7 spades=1-\sum_{r=0}^{6}\binom{18}{r}(\frac{3}{4})^{18-r}(\frac{1}{4})^r

The probability of drawing at least 7 spades=0.139
