The probability that a restaurant passes itshealth department inspection is 0.94. Theowners of 58 restaurants are surveyed to seeif their restaurants passed inspection. Find the standard deviation. A) 1.8245 B) 2.1040 C) 1.8086 D) 1.8655 E) 2.3589

Let x represent the dollar amount spent on supermarket impulse buying in a 10-minute (unplanned) shopping interval. Based on a newspaper article, the mean of the x distribution is about $34 and the estimated standard deviation is about $9. You can usee Part A and B as a reference, but I do not need help with answering them.   c) Let us assume that x has a distribution that is approximately normal. What is the probability that x is between $32 and $36? (Round your answer to four decimal places.)   (d) In part (b), we used x, the average amount spent, computed for 60 customers. In part (c), we used x, the amount spent by only one customer. The answers to parts (b) and (c) are very different. Why would this happen? Select one of the options:   A. The standard deviation is smaller for the x distribution than it is for the x distribution. B. The mean is larger for the x distribution than it is for the x distribution.     C. The standard deviation is larger for the x distribution…

The NJ Department of Health has reported the average life span of NJ residents is 81 years. If the standard deviation is σ = 4 years, what is the probability of a person living to at least 92 years of age?

According to the US energy administration, the mean monthly household electric bill in the united states is $99.70 with a standard deviation of $20. given that household electric bills follow a normal distribution, what is the probability that a randomly chosen household electric bill: c) is between $85.50 abd $110.50? d) is either higher than $105 or less than $90?

A survey was conducted to measure the height of Canadian men. In the survey, respondents were grouped by age. In the 20-29 age group, the height was normally distributed, with a mean of 69.2 inches and a standard deviation of 2.9 inches. A study participant is randomly selected.  a) Find the probability that his height is less than 66 inches.  b) Find the probability that his height is between 66 and 72 inches. c) Find the probability that his height is more than 72 inches. d) Find P10 , the 10th percentile please show all steps using excel formulas
