Approximately 58% of families in a town own at least two pets. A sample of 82 family were polled and asked whether they own at least two pets. Compute the standard deviation . Round to four decimal places. Compute the critical value corresponds to the proportion of sampled family who own at least two pets is 0.59. Round to four decimal places. Compute the critical value corresponds to the proportion of sampled family who own at least two pets is 0.63. Round to four decimal places. Find probability that the proportion of sampled family who own at least two pets is between 0.59 and 0.63. Round to four decimal places.

58 - 1 - p = 0.42 - n = 82 Calculate sigma p cap: σ p cap = √(p * (1 - p) / n) σ p cap = √(0.58 * 0.42 / 82) σ p cap = √(0.2436 / 82) σ p cap = √0.00296951 σ p cap ≈ 0.0545 Show more…

A sample of 100 residents was selected from all of the residents in a large city to estimate the average number pets they own. The sample mean, x̄, was 1.91 pets. Suppose μ, the true mean number of pets owned by residents in the city, is 1.75 pets with a standard deviation, σ, of 1.1 pets. What is the mean and the standard deviation of the sampling distribution of the sample mean? The mean is 1.75 pets and the standard deviation is 0.011 pets. The mean is 1.91 pets and the standard deviation is 1.1 pets. The mean is 1.75 pets and the standard deviation is 0.11 pets. The mean is 1.91 pets and the standard deviation is 0.11 pets.

The proportion of households in the United States that own both a cat and a dog is 0.20. Suppose you randomly pick one household at a time until you find a household that owns both a cat and a dog. What is the probability that you pick a household that owns both a cat and a dog on your first trial? What is the probability that you pick the first household that owns both a cat and a dog on your fourth trial? (Include 4 decimal places in your answer) What is the expected number of households you will have to pick to obtain the first household that owns both a cat and a dog? What is the standard deviation of the number of households you will have to pick to obtain the first household that owns both a cat and a dog? (Include 4 decimal places in your answer.)

Estimating the Standard Deviation: Veterinary Science How much should a healthy kitten weigh? A healthy 10-week-old (domestic) kitten should weigh an average of $\mu=24.5$ ounces with a $(95 \% \text { of data) range from } 14 \text { to } 35$ ounces. (See reference in Problem $33 .$ ) Let $x$ be a random variable that represents the weight (in ounces) of a healthy 10 -week-old kitten. Assume that $x$ has a distribution that is approximately normal. (a) Estimate the standard deviation of the $x$ distribution. Hint: See Problem 31 (b) What is the probability that a healthy 10 -week-old kitten will weigh less than 14 ounces? (c) What is the probability that a healthy 10 -week-old kitten will weigh more than 33 ounces? (d) What is the probability that a healthy 10 -week-old kitten will weigh between 14 and 33 ounces? (e) Inverse Normal Distribution A kitten whose weight is in the bottom $10 \%$ of the probability distribution of weights is called undernourished. What is the cutoff point for the weight of an undernourished kitten?
